walmart.com

[This review was collected as part of a promotion.] This Thames Kosmos Glow In The Dark Lab is seriously fun and so educational, as it's a science stem kit recommend for ages 8 and up. This was perfect for my homeschooled daughter and she had a blast with it! This kit has multiple different experiments for the kids to do with easy to read instructions and only requires a few basic common items from the house and everything else is included in the box. This Kept my daughter busy for awhile and also very happy! Highly recommend!

Amazing and fun!

[This review was collected as part of a promotion.] My son and I really enjoyed this glow in the dark lab set. Fun experiments for him to do on his own or I could join in. We were really happy with the ease of the instructions and the ability to do 6 different experiments. He made the glow in the dark chalk first and it was very easy and fun to do. Great molds and they dried fast so he could see his work finished quickly. He's been playing with it everyday and loves it. Highly recommend for kids to have something to do while stuck inside.

Fun experiments

[This review was collected as part of a promotion.] We are always looking for toys that are not only fun, but offer a educational twist to playtime. That's why we love this Glow-in-the-Dark Science Lab! There is nothing better than seeing your child's face and eyes light up when creating experiments. This kit teaches science, and my daughter just loves the glowing sidewalk chalk and glow sticks. It keeps her entertained for hours. I highly recommend this and will be buying similar kits in the future- double thumbs up!

Educational playtime!

[This review was collected as part of a promotion.] Thames Kosmos Glow In The Dark Lab is very Neat to play with. It brings out the scientist is children. I didn't und myself enjoying it as well. This product is highly recommend and it's so much fun to make different glow stuff. It is also a learning tool .

Very Neat

[This review was collected as part of a promotion.] This is perfect for 3rd graders! Comes with 6 ideas, you will only need to buy a white flower , 1 AAA battery and plenty of newspaper..This reminds me of a stem project..After you make molds and let them sit, you can use as chalk..Overall a good science project for eager little minds

Love Science

[This review was collected as part of a promotion.] I got this lab for my daughter. She likes to do experiments. She had fun mixing the powder into water and then using the blacklight to see it glow. She used the tray that came with it to make molds that glow in the dark. The molds all look the same color under the blacklight, even though some were yellow and some were pink. The instructions were very clear and included steps for six different experiments. It's a great kit for elementary school aged kids.

My Daughter Loves It!!

[This review was collected as part of a promotion.] My 8 year old granddaughter, myself and her mom spent a dreary Sunday afternoon creating these neat glow in the dark projects. The Thames Kosmos Glow In The Dark Lab was a lot of fun. Definitely needs the adult with the child for the younger ones. Chloe was thrilled when after 3 hours her treasures were hardened. We really had a lot of fun with this.

Fun!

[This review was collected as part of a promotion.] A box with a couple of supplies and full opportunity to create an interest in science. Great experiments. Really useful for hours of entertainment with the kids. My daughter loved the one to create neon chalk. The supplies even though you might think won't be enough, will prove you wrong. You only need a little per experiment then you reuse what you used on the previous one. Worth every penny. Awesome gift option as well.

Great way to create interest in science

[This review was collected as part of a promotion.] NOTE: For the blacklight photo I shared, I needed to use my personal UV flashlight. The small one included with the kit works, but it did not emit enough light for me to adequately photograph the experiments to proper effect.

This kit is labeled as glow-in-the-dark. I would say that misrepresents what I consider to be glow-in-the-dark. Definitions.com defines glow-in-the-dark as “an item or product that give a glow of light when used at night.” This DOES NOT. The kit comes with a small UV flashlight that allows your experiments to seem as if they glow. But once the light is removed, there is no phosphorescent effect at all, so I would recommend renaming this as a Fluorescent UV Science Lab kit. 

Overall, we were disappointed in this item. It literally did not live up to its name. Perhaps working with phosphorescent materials would not be safe for children, I don't know, but florescent materials is NOT the same thing. Lots of items "glow" under a blacklight, so overall, besides the fun of making our own chalk that is unfortunately too light to color with and will not glow in the dark, my kids and I were disappointed in this kit.

The contents include:
1. A firm plastic molding tray to make your own chalk pieces. The shapes include a beaker, a dolphin, a star, a crystal, and a frog. The tray is solid plastic and could be used many times.
2. Pink and Yellow/Green Fluorescent pigments. Both containers are about ¼ full of the powdery pigment: more than enough for your initial experiments.
3. Plaster. This comes in a bag and of course is rather dusty. Despite being very careful to not make a mess and having a small hole cut in the bag, we still managed to spill some. Definitely follow directions and use on old plastic cloth or newspapers if you are pouring inside your house. The plaster makes fine chalk pieces that we allowed to dry overnight, and they were easily removed and very pretty. In my reference photo you see a sheet of paper on the table which my kids wrote on with the pink chalk. It leaves a faint color tint on the paper, so you can't quite write secret messages. It does, however, reflect the UV light well, and our pictures illuminated well with the blacklight. We only made the pink chalk because my kids were not impressed enough to go through the messy process of making a yellow batch.
4. Lab equipment. You receive two test tubes with lids, a measuring cup, a stir stick that resembles a nail file, and two paper test tube holders you tape together. The equipment supplies met our needs to perform the experiments and are definitely reusable. 
5. UV Flashlight. The flashlight included has a very small bulb and does not emit much light. It requires use of a screwdriver to remove the back, and you must provide a AAA battery. Luckily, I already owned a UV flashlight, so we used both in our experiments. Mine emits more light, and so gave better results, but the one provided is certainly sufficient, and I would not recommend buying you own UV flashlight to use for this kit.
6. Glow-in-the-dark stickers. I tried using the UV flashlight to “charge” these stickers, and I held them up to a 60-watt bulb to try charging them. They do not appear to be actual glow-in-the-dark stickers, but reflective stickers in UV light. There are 15 stickers on the page of various space-related and animal shapes.
7. Instructional manual. It has 10 panels. The first three include content lists and warnings about proper use of materials. The fourth tells you how to put a battery in the flashlight. The other pages provide instructions for materials.
8. Please note you are expected to buy additional materials to do all the experiments. They include white flowers, tonic water, and chestnut tree bark (I could not find the bark locally).

The experiments:
1. The first experiment will also be used for another. You mix a little of the fluorescent pigment in water in the test tubes. You see a really neat effect with the use of the UV light. The instructions also explain how fluorescent pigments “glow”.
2. The second experiment you mix up the plaster and pour the fluorescent solution into the mix. We used the stir stick to transfer the plaster solution into the plastic mold to make our own chalk. Directions say it dries in four hours. We allowed ours to dry overnight and they were very cute. 
3. The third experiment expects you to place white flowers in water with the fluorescent powder stirred into it, wait a few hours, and then see how the flowers are drinking up the solution. The petals should reflect a new color under the UV light. Perhaps we did not put enough solution into our water (I used two spatula tips though the directions only called for one), but we saw no change in our daisies or white Gerberas. We waited four days and still no change. We have done a similar experiment with food coloring in the past to great effect, but with this experiment we saw no change. The instructions do provide a nice diagram of a plant's stalk so that you can see just how flowers “drink” and why the color should move throughout the plant.
4. The fourth experiment asks you to draw with your chalk and use the UV light.
5. The fifth experiment asks you to use tonic water, chestnut bark, and items from around your home to see what items might be UV-active. It also explains that the quinine in tonic water is what allows it to glow blue under UV light, and that scorpions and other natural materials also shine under UV light.
6. The final experiment asks you to brake open your experiment box, create a paint using your fluorescent materials and to use that and your chalk and your stickers to create a backdrop to showcase your flowers and tonic water experiments. 

Overall, this kit was a very nice idea, but I do wish that the chestnut bark and some tonic water could have been included. I also wish the UV light could have been a little brighter. But most of all, I wish the name hadn't set up the wrong expectations for us. Anyone hoping to make items that will be able to glow on their own in the dark will be sorely disappointed.

Not quite what I expected

[This review was collected as part of a promotion.] Let me just say we spent more time on cleaning up the messes from each experiment than we did on actually doing the experiment. Definitely plan ahead it doesn't include all materials needed & in order to complete any of the experiments you have to go in order. For example you have to complete the first experiment in order to complete the second experiment. The tiny screws in the UV light wouldn't come out so we couldn't even use it. The experiments were very messy, not planned very well, and honestly the experiments didn't turn out well. My daughter was a little frustrated due to the fact we didn't have the materials to complete the experiments but than we we got them we couldn't get the light to work. The measuring tools to use for the experiments are small & reading the numbers when measuring what you need were not the easiest to read. We definitely enjoyed reading the fun facts along the way when completing each experiment.

Looks can be deceiving, very messy!
