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.

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!

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.

The design of this is perfect. It made it super easy to do this experiment. It shot up more than 10 feet in the air. Products are reusable. Eat and simple instructions!

Was a lot of fun with my son and his friends. Easy to use to make the mentos and coke experiment easier to execute. Have to hold the release trigger as you load it up, but not difficult to do. Small kids will need some help.

Do you want a neat, soda-hair bun, or are you going for the wild soda-hair explosion? The caps let you customize your fizzy fashion.The chemistry magic was so real; I felt like I was in a wizarding school for soda sorcery. Forget Hogwarts; I was mastering the art of carbonated chaos!

My son is obsessed with "science experiments." This device is perfectly designed for the coke and mentos experiment. It operates intuitively, I just cut my 7 year old loose with a couple packs of mentos and some off brand 2 liter sodas and he entertains himself. Build quality could be better but for the price it is appropriate.
