Glow-in-the-dark science kits combine hands-on experiments with materials that glow after exposure to light, but the best choice depends on whether a child wants variety or one focused project. I’d put the National Geographic Glow-in-the-Dark Mega Science Experiment Kit in the best-overall position for its broad experiment format, while the Thames & Kosmos Glow-in-the-Dark Science Lab STEM Experiment Kit stands out for a more lab-centered STEM experience. For a single display-worthy activity, the National Geographic Glow-in-the-Dark Solar System Model Kit offers a different kind of appeal. The main tradeoffs are project variety versus depth, guided activities versus open-ended play, and glow effects versus the kit’s underlying science value. Read on for a ranked breakdown and advice on matching a kit to a child’s age, interests, and tolerance for setup.

Key Takeaways
- Multi-project kits lead on variety: The National Geographic Mega Science Experiment Kit and Thames & Kosmos Science Lab are the broadest choices for children who want more than one activity.
- Focused kits fit specific interests better: The solar system, crystal-growing, bouncy-ball, rock-and-dinosaur dig, shark dissection, and T. Rex dissection kits each center on a particular subject or hands-on outcome.
- The glow effect is not the whole value: A kit is a stronger pick when its science activity remains engaging even after the glowing materials have been charged and viewed.
- Age and project style shape the best match: The ages 8–12 kit gives families an explicit age range, while dig and dissection formats suit children drawn to tactile discovery and anatomy themes.
- Big kits are not automatically better: A broad experiment set can offer more variety, but a single-purpose kit may be easier to choose, set up, and finish for a child with a clear interest.

More Details on Our Top Picks
Smartivity Glow-in-the-Dark Science Kit for Kids
With 20 glow-in-the-dark experiments spanning chemistry and physics, this is the broadest activity-led pick in this group. Its mix of a glowing lava lamp, soap, stick, and spinner gives kids more variety than the National Geographic Jumbo Glow-in-the-Dark Crystal Growing Kit, which centers on one slow-growing project. Step-by-step instructions, instructional videos, and a messy mat make it easier to set up a sequence of activities at home, while the parts guarantee helps if a piece is broken or missing. The tradeoff is that the activity count does not mean every experiment is independent play: younger children may need adult help. It also suits families who want repeated experiments better than kids looking mainly for a collectible display or a single geology project.
Pros:- Includes 20 experiments across chemistry and physics
- Step-by-step instructions and instructional videos support setup
- Messy mat is included for activities at home
- Parts guarantee addresses broken or missing pieces
Cons:- Younger children may need adult assistance

Glow in the Dark Science Experiments Kit for Kids Ages 8–12
This kit is a straightforward choice for ages 8–12 who want several chemistry and physics activities without a narrow theme. Its 15+ experiments, including glowing slime and luminous reactions, offer more variety than the National Geographic Jumbo Glow-in-the-Dark Crystal Growing Kit, which focuses on a single crystal project. An illustrated manual gives children a visual sequence to follow and frames the activities around observation and problem-solving. The tradeoff is a more limited support package than Smartivity: the listed included component is an instruction manual, rather than a messy mat and instructional videos. Adult guidance may still be needed for some experiments, so this fits best when a grown-up is nearby rather than when kids need a fully self-directed kit.
Pros:- Offers more than 15 hands-on chemistry and physics activities
- Includes an illustrated step-by-step instruction manual
- Activities are designed to build observation, logical thinking, and problem-solving
- Compact box dimensions make it easier to store than a large project setup
Cons:- Adult guidance may be needed for some experiments
- Listed kit components do not include a messy mat or instructional videos
Best for: Families with children aged 8–12 who want a range of guided glow-in-the-dark activities and can provide help when experiments call for it.
Not ideal for: Younger children needing broader age coverage or families wanting extras such as a messy mat and video guidance.
- Brand:PW
- Age range:8–12 years
- Activities:15+
- Theme:Chemistry
- Material:Polyvinyl Alcohol (PVA)
- Included components:Instruction manual
- Dimensions:9.65 x 7.68 x 1.97 inches

Our verdict“Pick PW for a varied, manual-led activity set for school-age kids, but choose Smartivity if video guidance and a messy mat matter more.”
National Geographic Glow-in-the-Dark Mega Science Experiment Kit for Kids
Rather than spreading its activities across a long list of general experiments, this kit combines crystal growing, slime, glowing putty, and wernerite. That mix gives kids several kinds of materials to explore, from a mineral specimen to hands-on compounds, making it a more varied materials experience than the National Geographic Jumbo Glow-in-the-Dark Crystal Growing Kit, which concentrates on crystals. The full-color guide explains why the materials glow, helping connect the visual result with the science behind it. It is designed for ages 8 and up and can suit home or classroom activities. Its tradeoff is a narrower activity set than Smartivity’s 20 experiments, and the age guidance makes it less suitable for younger children. Choose it for geology and material variety, not the greatest experiment count.
Pros:- Combines crystal growing, slime, putty, and a wernerite specimen
- Full-color guide explains the science behind the activities
- Suitable for home, classroom, or family use
- Offers more material variety than a crystal-only kit
Cons:- Recommended for ages 8 and up

- Model number:NGMEGAGID
Our verdict“Choose this National Geographic kit for a guided mix of glowing minerals and hands-on materials, rather than the widest experiment count.”
National Geographic Glow-in-the-Dark Solar System Model Kit
This is the standout choice for kids who want a glowing science project they can display, not a succession of chemistry experiments. Building and painting the sun and all eight planets turns the kit into an astronomy craft, while movable arms let children rearrange the model after assembly. Its glow-in-the-dark accent paint adds a nighttime detail; the included fact poster and instructions give the project an educational anchor. Compared with the National Geographic Mega Science Experiment Kit, this has a more defined subject and a lasting model instead of slime, putty, and mineral activities. That focus is also the tradeoff: assembly and painting take time, and it offers less experimental variety than Smartivity. It suits patient makers who enjoy model-building more than mixing materials.
Pros:- Builds a model featuring all eight planets and the sun
- Movable arms allow the planets to be rearranged
- Includes glow-in-the-dark accent paint and painting supplies
- Fact poster and instructions connect the craft to astronomy
Cons:- Requires assembly and painting
- Provides a single model-building project rather than a varied experiment set
- Recommended for ages 8 and up
Best for: Children aged 8 and up who enjoy painting, assembling models, and learning about the solar system through a display project.
Not ideal for: Kids seeking multiple hands-on chemistry experiments or a ready-to-use activity without assembly and painting.
- Brand:Blue Marble
- Age range:8 years and up
- Included:Planets, sun, 6 paint colors, glow-in-the-dark accent paint, brush, palette, decals, fact poster, and instructions
- Features:Glows in the dark; movable planet arms
- Dimensions:7.09 x 2.36 x 12.01 inches
- Weight:0.3 kg
- Material:Plastic
- Model number:NGSOLARSYS
Our verdict“Choose this kit for an astronomy-minded child who wants to build and display a glowing solar system, not for broad experiment variety.”
National Geographic Jumbo Glow-in-the-Dark Crystal Growing Kit for Kids
For a child drawn to how crystals form, this kit keeps the activity focused: grow a jumbo crystal that glows in the dark, then use the learning guide and fluorite specimen to extend the geology angle. Its few-days growing period gives the project a sense of anticipation, but it also means this is not a quick activity. Compared with the National Geographic Mega Science Experiment Kit, it offers a more concentrated crystal-growing experience rather than adding slime and putty; Smartivity is a better match for families after many experiments in one box. The included specimen and guide add useful context beyond the growing task. The main tradeoff is patience: children wanting immediate, varied experiments may lose interest while the crystal develops.
Pros:- Grows a jumbo crystal with a glow-in-the-dark feature
- Includes a fluorite specimen for examining a real mineral
- Learning guide adds context about crystal science
- Designed as an accessible hands-on STEM activity
Cons:- Crystal growth takes a few days
- More focused than mixed-activity options such as the National Geographic Mega Science Experiment Kit
Best for: Children aged 8 and up who are curious about crystals and can stay interested in a project that develops over several days.
Not ideal for: Kids who want immediate results or a broad sequence of experiments rather than one central crystal-growing activity.
- Age range:8 years and up
- Educational objectives:Exploratory skills, hand-eye coordination, and STEM learning
- Included components:Crystal growing kit, detailed learning guide, and fluorite specimen
- Item dimensions:7.24 x 2.37 x 10 inches
- Item weight:380 g
- Theme:Earth science
- Number of items:1
Our verdict“Pick this kit for a patient young geology enthusiast who wants to grow one substantial glowing crystal and learn about minerals.”
Blue Marble Glow-in-the-Dark Bouncy Ball Science Kit
For a group that wants to make and keep a glow-in-the-dark creation, this kit offers more repeatable play than the excavation kits in this roundup. It makes up to 45 bouncy balls with six polymer powder colors and five molds, giving children room to share and compare results. The four-step process includes a 10-minute water soak, while the learning guide introduces the STEM behind the activity. Compared with the Thames & Kosmos Glow-in-the-Dark Science Lab, this pick centers on one project rather than five different experiments, but its potential batch size suits parties and playdates better. The tradeoff is that the two powder packets are finite, and soaking and drying mean the activity is not instant. I’d choose it for shared making, not for kids seeking varied experiments.
Pros:- Makes up to 45 balls, making it well suited to sharing
- Six polymer powder colors and five molds offer variety within the project
- Glow-in-the-dark balls give the finished activity a playful use after making
- Learning guide explains the science behind the process
Cons:- Powder is limited to two packets, so the maximum output depends on careful use
- The process requires a 10-minute water soak and additional drying time
- Focuses on making one kind of object rather than exploring several experiment types
Best for: Families or activity leaders who want a glow-in-the-dark project that can produce many take-home creations for a playdate or party.
Not ideal for: Children who want several different kinds of experiments, or anyone expecting a quick activity without soaking and drying time.
- Recommended age:6 years and up
- Balls to make:Up to 45
- Polymer powder colors:6
- Molds:5
- Included components:2 packets of glow-in-the-dark polymer powder, 5 molds, instructions
- Educational objective:STEM
- Dimensions:6.06 x 2.36 x 6.18 inches
- Weight:10.08 ounces
Our verdict“Choose this kit for a group-friendly ball-making activity, but pick the Thames & Kosmos lab if variety of experiments matters more than batch size.”
National Geographic Glow-in-the-Dark Rock and Dinosaur Dig Kit
This is the most approachable choice here for younger children: the stated age range starts at 4 years, and the central task is clear—excavate six glow-in-the-dark discoveries. The dig brick holds three rock specimens and three dinosaurs, with a tool, LED light, and illustrated learning guide to give the activity a discovery-and-identification structure. Compared with the National Geographic Glow-in-the-Dark T. Rex Dissection Lab, this kit offers a broader mix of finds but does not lead to assembling a larger model. It is also less experiment-focused than the Thames & Kosmos lab. The main drawback is the excavation itself: breaking into the brick can scatter debris, so a tray and adult supervision may help. I’d favor it as a first glow-in-the-dark science activity, not as a tidy tabletop project.
Pros:- Age range begins at 4 years, younger than the other kits in this batch
- Includes six discoveries: three rocks and three dinosaurs
- Comes with an excavation tool, LED light, and full-color learning guide
- Combines hands-on digging with specimen facts
Cons:- Excavating the brick can create debris and calls for a cleanup plan
- The activity centers on uncovering specimens rather than building a lasting model
- Offers one excavation project rather than multiple experiment formats
Best for: Caregivers seeking a first hands-on glow-in-the-dark STEM activity for a preschooler or young elementary-age child who enjoys digging and collecting finds.
Not ideal for: Families who need a low-mess activity or children who prefer assembling a finished model or conducting several distinct experiments.
- Age range:4 years and up
- Discoveries:3 glowing rock specimens and 3 glowing dinosaurs
- Included components:Dig brick, dig tool, LED light, full-color learning guide
- Educational objective:STEM
- Language:English
- Dimensions:7.08 x 2.36 x 12 inches
- Model number:RTNGGIDDIG
Our verdict“Pick this for a younger child who wants an accessible dig-and-discover activity, and skip it if cleanup or model assembly is a priority.”
Thames & Kosmos Glow-in-the-Dark Science Lab STEM Experiment Kit
Among these five options, this kit has the clearest range of science activities: its five experiments explore glowing materials, light, and phosphorescence, including making neon chalk and glow sticks. The included UV flashlight and yellow and pink pigments help children see how the materials respond, while the box can serve as a blacklight showcase. That variety sets it apart from the Blue Marble Bouncy Ball kit, which focuses on producing one type of creation, and from the National Geographic dig and dissection kits, which center on excavation. The tradeoff is a higher stated starting age of 8 years and a more involved assortment of small components. It also needs one AAA battery, which is not listed among the included components. I’d choose it for older kids who want to test several glowing effects rather than repeat one tactile project.
Pros:- Five activities explore more than one aspect of glowing materials and light
- Includes a UV flashlight and yellow and pink UV pigments
- Projects include making neon chalk and glow sticks
- Kit box doubles as a blacklight showcase
Cons:- Requires one AAA battery
- The range of small parts and activities may need adult help with setup and organization
- Its age range starts at 8, older than the dig and dissection kits
Best for: Families with children 8 and up who want several hands-on activities about glowing materials and light in one kit.
Not ideal for: Younger children, or buyers seeking a simple excavation or single-project activity with fewer components to organize.
- Age range:8 years and up
- Activities:5
- Included components:Plaster powder, plastic mold, glow-in-the-dark stickers, UV flashlight, test tube stand, small parts, yellow and pink UV pigments, beakers, capped test tube, brush, spatula, manual
- Battery:1 AAA
- Material:Plastic
- Dimensions:8.8 x 2.5 x 11 inches
- Weight:12.8 ounces
- Warranty:1 year against manufacturer defects
Our verdict“Choose this for an older child who values varied glow experiments; choose a National Geographic dig kit for a simpler excavation-led activity.”
National Geographic Glow-in-the-Dark Shark Dissection Kit for Kids
This kit turns glow-in-the-dark pieces into a focused anatomy activity: children dissect a synthetic great white shark model to find four organs and eight skeletal pieces, then can repeat the activity with the included gel refill. Its learning guide adds shark anatomy and ocean ecology, giving the dissection more context than a straightforward specimen hunt. Compared with the National Geographic Glow-in-the-Dark T. Rex Dissection Lab, the shark kit leans toward marine biology, while the T. Rex option ends with a 9.5-inch assembled skeleton. Neither uses a real specimen, so children seeking authentic animal materials should skip both. This kit’s appeal depends on interest in anatomy and the dissection format; it is less varied than the Thames & Kosmos lab. I’d pick it for a child keen on ocean life and repeatable, guided exploration.
Pros:- Glow-in-the-dark skeletal pieces make the anatomy discovery distinctive
- Includes four organs and eight skeletal pieces to uncover
- Gel refill allows a second dissection
- Learning guide covers both shark anatomy and ocean ecology
Cons:- Uses a synthetic shark model rather than a real specimen
- The activity is centered on one dissection format
- Does not produce an assembled display model like the T. Rex kit
Best for: Children 6 and up who are especially interested in sharks, marine ecology, and taking apart a model to learn its anatomy.
Not ideal for: Buyers seeking a real specimen, a finished display model, or several different kinds of glow-in-the-dark experiments.
- Age range:6 years and up
- Model:Great white shark dissection lab
- Contents:Shark mold, 4 organs, 8 skeletal pieces, gel refill, dissection tool, tweezers, instructions, learning guide
- Educational objective:STEM
- Dimensions:7.09 x 2.36 x 12.01 inches
- Weight:14.08 ounces
- Number of items:1
Our verdict“Choose this for a young ocean-life enthusiast who wants repeatable model dissection, not for a child seeking a real specimen or a build-and-display result.”
National Geographic Glow-in-the-Dark T. Rex Dissection Lab Kit
Where the shark kit focuses on uncovering anatomy, this option adds a clear finish: children excavate glow-in-the-dark bones and assemble a 9.5-inch T. Rex skeleton. The included gel refill supports another dig, so the kit offers a repeat session as well as a model-building payoff. That makes it a stronger pick for dinosaur fans who like to display what they uncover; the National Geographic Glow-in-the-Dark Shark Dissection Kit is better matched to children drawn to ocean ecology and shark anatomy. Both use synthetic models, and this one is not a real fossil excavation. Its scope is also narrower than the Thames & Kosmos lab’s five experiments. I’d choose it for a child who wants a guided dinosaur dig that ends in assembly, while skipping it if varied science activities matter more than one themed project.
Pros:- Combines excavation with assembly of a 9.5-inch skeleton
- Glow-in-the-dark bones make the completed model a distinctive result
- Includes a gel refill for another excavation
- Learning guide covers T. Rex facts and anatomy
Cons:- The dinosaur mold and skeleton are synthetic rather than real fossils
- The activity centers on one dinosaur-themed project
- Less suited to children who prefer experiment variety, such as the Thames & Kosmos lab
Best for: Children 6 and up who love dinosaurs and want an excavation activity with a glow-in-the-dark skeleton to assemble and display.
Not ideal for: Children looking for a real fossil dig, several different experiment types, or a project focused on animals other than dinosaurs.
- Age range:6 years and up
- Skeleton model length:9.5 inches
- Included components:Dino mold, glow-in-the-dark skeleton, gel refill pack, dissection tool, tweezers, instructions, learning guide
- Educational objective:STEM
- Material:Plastic, paper
- Dimensions:7.09 x 2.36 x 12.01 inches
- Weight:0.52 kg
- Model number:RTNGTREXLAB
Our verdict“Pick this for a dinosaur fan who wants to dig, assemble, and display a glowing skeleton; choose the shark kit for a marine-biology focus.”
How We Picked
I ranked these kits by how well they pair a visible glow-in-the-dark payoff with a worthwhile science activity. I weighed the number and variety of projects, how clearly the kit’s focus is communicated, the likely appeal of its hands-on format, and whether the activity offers more than a novelty effect. I also considered how readily a parent can match each kit to a child’s interests, age, and preference for building, mixing, digging, or examining.
The broad experiment kits rank ahead for families seeking repeat activity and range, while focused kits earn their place when they offer a distinctive subject or outcome. The Mega Science Experiment Kit leads as the broadest all-rounder; the Thames & Kosmos lab is a strong alternative for a lab-style experience. Single-project kits rank by how well their specific theme serves a clear buyer need, not by how many activities they claim to include. Product details can vary by edition, so I recommend checking the listed age guidance, included materials, and adult-supervision notes before buying.

Factors to Consider When Choosing Glow In The Dark Science Kits
Before choosing, I’d look past the glow effect and match the kit’s activity style to the child who will use it. These distinctions can help prevent a kit from feeling too simple, too involved, or less reusable than expected.
Choose Variety or One Strong Theme
Start by asking whether the child enjoys sampling different activities or prefers to stay with one subject. A multi-experiment kit may suit a curious child who likes switching tasks, while a crystal, space, or fossil-themed kit can hold attention through a clear goal. A common mistake is buying the largest-looking set when the child is passionate about only one topic. More activities can mean more materials to organize and more instructions to follow. A focused kit may deliver a more satisfying project, even if it does not provide the same range. Let the child’s interests guide the format, not just the number of experiments.
Check What the Glow Adds to the Activity
Glow-in-the-dark materials can create a memorable reveal, but the science activity should still have a purpose before the lights go out. Consider whether the child will make, observe, build, or investigate something, rather than simply view a glowing object. Glow effects usually depend on exposure to light, so the result may vary with how the materials are charged and the viewing conditions. If a child mainly wants a luminous decoration, a model kit may be a better fit than a sequence of experiments. For a child focused on learning, prioritize clear scientific ideas and repeatable observations. This keeps the glow as part of the experience rather than the whole reason to use the kit.
Match the Work to the Child’s Independence
Age guidance is a useful starting point, but it does not tell the whole story about how much help a child may need. Think about their comfort reading instructions, measuring or mixing materials, and keeping a workspace organized. Some children enjoy parent-child collaboration; others want to manage a project more independently. Check the packaging for adult-supervision notes and any household supplies that may be needed. Buying a kit that is too advanced can turn an exciting activity into a frustrating one, while a very simple project may not hold an older child’s interest. Choose for the child’s practical skills as well as their age.
Think About Cleanup and Workspace
Digging, mixing, and dissection-style activities can feel more immersive than building a model, but they may also need more preparation. Before buying, consider whether the project calls for a protected surface, a bowl or tray, or a place to store materials between sessions. A small, tidy workspace can make a difference for families who cannot leave a project set up. Models and display projects may be easier to keep once complete, while experiments can involve materials that are used up. Read the included-material list and instructions when available rather than assuming everything is in the box. Practical setup needs can matter as much as the activity itself.
Look for Repeat Use, Not Just More Pieces
A high piece count does not automatically mean a kit will last longer. Some projects can be repeated, while others create one main result or use materials that are depleted during the activity. If the child likes revisiting a project, check whether the kit supports repeated observations or provides more than one attempt. A finished model or specimen can extend interest as a display, though it may not offer the same hands-on reuse. Families seeking ongoing activity may prefer a broader experiment set, while a child who loves completing and showing a project may be happier with a focused kit. Decide what “lasting value” means for your household before comparing contents.
Treat Subject Matter as a Buying Filter
Glow-in-the-dark kits in this roundup range from space and crystals to dinosaurs, rocks, sharks, and a bouncy-ball experiment. That variety makes a child’s favorite subject a practical way to narrow the field. Dissection and dig formats can be especially appealing to children who like tactile discovery, but they may not suit a child who prefers clean construction projects. Likewise, a model may please a builder but disappoint someone who wants to mix or investigate. Do not assume every child drawn to glowing effects will enjoy every science format. Choosing the right theme often matters more than choosing a kit with the broadest description.
Frequently Asked Questions
Which kit should I choose if I want several different activities rather than one project?
I’d start by comparing the National Geographic Mega Science Experiment Kit with the Thames & Kosmos Science Lab STEM Experiment Kit, since both are positioned as broader experiment experiences. The Mega kit is the stronger all-round choice for variety, while the Thames & Kosmos option may suit a child who prefers a more lab-centered format. Check the current box contents and instructions, because included activities can differ by edition. If the child has one strong interest, a focused kit may be more engaging than a larger assortment. Choose based on the kind of activity they are likely to finish and revisit.
Are glow-in-the-dark kits suitable for a child who mainly wants a science lesson?
They can be, but the glow effect alone does not tell you how much science a kit teaches. Look for activities that involve building, observing, comparing, or investigating, and read the instructions or product details for the concepts covered. The broader experiment kits offer more room for different activities, while focused kits can connect a clear subject—such as space, crystals, or anatomy—to a hands-on task. A model or glowing object may emphasize making and display more than repeated experimentation. If learning is the priority, select the kit by its activity and explanation, with the glow as an added feature.
How can I tell whether a kit will need adult help?
Check the stated age range, adult-supervision notes, and instructions for steps involving measuring, mixing, tools, or workspace preparation. Age guidance is not a guarantee that a child can complete every part alone, since reading confidence and attention to directions vary. A kit with several experiments may call for more help with sorting materials and following separate steps than a single focused project. Dig or dissection-style activities may also require an adult to help manage the work area. If independent play matters, favor a project whose setup and instructions seem manageable for that child.
Should I choose a single-project kit or a multi-experiment kit as a gift?
For a child whose interests are broad or not yet clear, a multi-experiment kit is the safer direction because it offers several ways to engage. If you know the child loves dinosaurs, sharks, space, crystals, or digging for finds, a themed kit can feel more personal and easier to get excited about. A single-project kit may also be easier to plan for when space or adult time is limited. Before gifting, check age guidance and whether the activity needs household supplies or supervision. The best choice is the one that matches the child’s preferred way to play, not simply the box with the most activities.
Do I need a dark room for the glow effect, and will it keep glowing indefinitely?
A darker viewing space generally makes a glow effect easier to see, and glow-in-the-dark materials typically need exposure to light beforehand. Brightness and how long the effect remains visible can vary with the material, charging conditions, and room lighting. I would treat the glow as a temporary part of the activity rather than a permanent light source. Check the product instructions for charging guidance and any care details specific to the included materials. If the child expects a continuously glowing display, a model kit may still be enjoyable, but set expectations that the effect may need recharging.
Conclusion
For the best overall, I’d choose the National Geographic Glow-in-the-Dark Mega Science Experiment Kit for its broad experiment format. The best alternative for a lab-focused child is the Thames & Kosmos Glow-in-the-Dark Science Lab STEM Experiment Kit. I’d treat the best value as the kit that matches a child’s interests and gets used—not the one with the most pieces—so the ages 8–12 experiment kit can make sense for families seeking a clearly age-framed option. For beginners, a focused project such as the solar system model or bouncy-ball kit may feel easier to approach than a large set. For specific interests, choose the crystal kit for growing, the rock and dinosaur dig or T. Rex kit for prehistoric themes, and the shark kit for anatomy. Match the project style, age guidance, and setup demands to the child, and the glow will be an appealing bonus to a science activity they actually want to do.
