Steve Spangler Science Geyser Tube Experiment, Chemical Reactions Science Experiments for Kids, Amazing Geysers with Soda & Mentos Candy, School, Camp, Homeschool Science Kits, Incl: 1 Tube

I got this Coke and Mentos tube for some backyard fun, and it completely exceeded our expectations! The setup was super easy, and the fact that it comes with Mentos included is a big plus. When we set it off, the reaction was incredible—the soda shot way higher than we thought it would! It was such an exciting and hilarious experience, perfect for kids and adults alike. Just make sure to do this outdoors and have a camera ready because it’s definitely a memory-maker. Highly recommend for anyone looking for a simple, thrilling, and educational activity. This little tube packs a big punch!

This is gonna be great fun with the grandkids! I like the three different nozzles to give us different geyser effects God bless

I purchased two of these for two of my grandkids. Make sure you read the directions and that you need a 2 Liter bottle of soda. They recommend diet soda so that it doesn't create a "sticky" mess. The set comes with four different style caps for different outcomes. If you are gifting this, make sure to include a couple bottles of soda as the kids (if they are like mine) will want to try it out immediately. The geyser of soda doesn't last long, but the kids still loved it and wanted to keep doing it.

These work great but they are extremely overpriced. I gave it 4 stars because the kids do enjoy it very much but it’s a shame that it is priced so ridiculously high for just a but of plastic. I haven’t seen any others that work like this so I went ahead and bought it anyway because it’s a good design.

This thing is so cool! We’ve tried to do our own before and it wasn’t as successful as this set! So worth the money both my kiddos loved.

Definitely worked out great and reusable. I'm a home school parent and always looking for new fun ways to learn and I loved this. 10/10 would recommend to everyone.

My child told me this was the best Christmas gift ever! I sized down to 16oz drinks for the experiments after seeing what was left in a 2 liter and bought two 6 packs so we have a small stock. He keeps asking to do it again! Trying to keep the experiments to one every few days for cost/waste, but he loves it!

We had so much fun with this on christmas morning. My son loved the spray options. Kid approved
