Thames & Kosmos Ooze Labs Chemistry Station Science Experiment Kit, 20 Non-Hazardous Experiments Including Safe Slime, Chromatography, Acids, Bases & More, Multi-Color

We bought this for our six year old this Christmas. He has had a blast with it. The instructions are easy to understand, but he still needs help from Dad. Quite a few of these experiments can be redone over and over. Our four year old enjoys helping too but most of all playing around with it after the experiment is done. I highly recommend this!

Super fun set, my 6 year old required help but it was fun for everyone

Got this for my 8-year-old daughter who's really into learning potions like Harry Potter in Snape's class, and requested more chemistry experiments. It was on sale for around $15 at the time, looked similar to the Magic Science kit but I liked how it had a whole lab setup.Comes with various test tubes with lids, pipettes, plastic stirring sticks, and little measuring cups, plus a plastic base with towers and test tube holders. You can move the test tube holders around however you want. There are a couple of clips to hold the laminated cards for the first 9 experiments, which makes them easy to read while doing the experiments.It did not include any gloves or safety glasses as some other kits seem to, but the experiments are overall pretty safe. I was mostly letting her do them on her own, while listening in and doing various cleaning around the kitchen, while occasionally looking in and reminding her to actually read the instructions again and make sure she wasn't skipping any.After doing the first 6 experiments, I asked her how much her friends would probably like this as a gift on a scale from 1 to 10, and she rated it an 87. Apparently her friends really love slime.But apart from the slime in the first two experiments, almost all of these are experiments you can easily do at home with baking soda, vinegar, water, oil, sugar, and food coloring. But considering I got it for around $15, I do think that's a good price for a nice setup of test tubes and a holder with nice instruction cards.Experiments:1. Glow in the Dark Slime: mix this powder with water, stir/shake it until it solidifies. Take into a dark room and see that it glows in the dark. My daughter didn't really want to touch it because it was way *too* slimy, so we transferred it into a baggie to poke at.These first few experiments used the same tall wide test tube, so we couldn't start doing the later ones while waiting for the first few. I wish they'd included more of those test tubes so we could do them at the same time. It was a little boring waiting for the slime to solidify.2. Thermocolor Slime: Same as before, mix this powder with water and stir/shake until it solidifies. Ours started out green and putting it in hot water did nothing, but then I realized maybe it was already too warm and tried putting it in ice water, so it turned blue again. Same as previous slime, it went in a baggie.3. Fizzy Fun Reaction: Citric Acid in one test tube, baking powder in the other, mix them together and it fizzes everywhere! No warning that it would foam, but we'd done this before in KiwiCo kits so she knew what was about to happen and held it over the sink. Easy experiment to do without this kit.4. Oozing Bubbles: Oil floating on water, add fizzy dye tablet and watch the colored water go up and then fall down again like a lava lamp. Doesn't last long, but it comes with two more tablets so you can repeat the experiment. (Or just get fizzy tablets from the store) Another easy experiment to do without this kit.5. Colorful Chromatography: Draw on this piece of filter paper with marker, then drop water onto the center and watch what happens as the water spreads out. A neat little art project that will take a few minutes.6. Rainbow in a Test Tube: She had a hell of a time dyeing the cups different colors, because it wanted her to make 6 colors out of 5 dye tablets, and also it wanted her to use only *part* of a tablet for this (and save the rest for future experiments). The tablets were solid enough that I ended up bringing out my meat mallet to smash them into crumbs, and there wasn't a good way to save the remaining crumbs separated from each other for future experiments. A different form factor for these dyes would have been better. Maybe two half-size tablets of each color instead! This experiment is also pretty easy to do without this kit, since it's just food coloring and sugar water.We stopped here on the first day after 2-3 hours of this because the next one wanted red cabbage that we didn't have and it felt like time for a break, but here's the remaining ones:7. Color-Changing Indicators: Make red cabbage liquid, and watch as it changes color when you add liquids of different pH. Interesting that the kit included citric acid and baking soda for experiment #3, but now that we're doing more acids and bases, it wants us to use our own from the kitchen. Why even include the first packets? This experiment is also easy to do without this kit, as all the chemicals are from my kitchen, they're just being mixed in this neat lab setup.8. Goopy Oobleck: Mix corn starch and water, play with this non-Newtonian fluid. This experiment barely even uses the lab, since you're mostly just mixing it in a bowl (not included in kit)9. Mixing Colors: Using the crumbs left over of the dye tablets from #6, make colored water in test tubes and then do this complicated setup where you use a flexible plastic tube attached to a syringe to move the colored water from the test tubes into an erlenmeyer flask. I guess it makes you feel like a scientist?10. The 10th card isn't an experiment, just an extremely simplified kid's periodic table that only includes the first four rows. I don't have a problem with this, they get the gist of it without getting overwhelmed by too many elements.The remaining experiments are in the booklet that comes with the kit:10. Oil and Water: Mix oil and water. See that they separate when you let them sit.11. Moooooving Colors: Use the same colored water from #9 (probably should save them from that experiment). Drop colors into milk in a petri dish, then add dish soap and watch the colors move.12. Chemical Foaming: Compare what happens when adding baking soda to vinegar water when one of the tubes has dish soap in it.13. Acid Detective: Try adding baking soda to various household liquids (milk, juice, oil, tea) to see if they're acidic or not.14. Powder Detective: Tell three identical white powders apart (powdered sugar, corn starch, baking soda) by seeing if they will dissolve in water and whether they react with acid.15. Self-inflating balloon: Put baking soda in a balloon (not included in this kit) and put it over a bottle (not included in this kit) and watch the balloon expand when the baking soda falls into the vinegar.16. Invisible Ink: I hope you saved that cabbage juice from experiment #7! Mix it with vinegar, use a cotton swab to draw on a piece of paper, let it dry, then write with baking soda water on the dry paper.17. Salty and Sweet Solutions: Look at salt and sugar crystals using a magnifying glass (not included in this kit) then dissolve them in water to see how many drops you need to use to dissolve them completely.18. Growing Salt Crystals: Make a supersaturated salt solution and put it in the petri dish for a couple of days to watch crystals form.19. Carbon Dioxide Fire Extinguisher: Light a candle! Then use the fizzy tablet to make carbon dioxide in a test tube and use the flexible tubing to direct the gas towards the flame to put it out.20. Separating Mixtures: Make dirt water. Use filter paper to filter the dirt out.

Great birthday party gift for a 6 year old boy or girl! Fun easy experiments to do at home.

My daughter wanted chemistry sets for Christmas! This set was awesome and she loved it! Perfect set for 9 year old. Instructions were clear enough for her to do the experiments on her own!

The kids enjoyed doing the experiments in this set. There is a nice variety of experiments and the set up makes them easy to do.

Has great experiments but didn't realize I was going to have to buy so many more things from the grocery store to do a majority of them.

This provided days and hours of entertainment for our 6 year old! Highly recommend if you’re ok with a little mess. Tip: I put foil under the set so if my son spilled something I didn’t worry about my counter getting messy and made clean up a breeze!
