Best pick for a gift !

  • Spectacular Fun – Went Higher Than Expected!
Style: Geyser 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! ... show more

  • Loads of Fun
Style: Extreme Geyser Tube
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. ... show more

  • So much fun
Style: Extreme Geyser Tube
The media could not be loaded. This thing is amazing! The kids love it. The only thing I don’t like is the red stopper isn’t secure so it could slip out of place before you are ready and drop the mentos.

  • Best experience
Style: Extreme Geyser Tube
I don't normally review things. We have been playing with the whole soda explosion stuff (along with other crazy messy stuff we can think of!) We used this on a 20oz bottle of diet soda with 4 candy's in our shower It sprayed so high and hard it created an umbrella-like cascade all over the bathroom Best. Experience. Ever. Sure it's now a sticky mess in our bathroom. But it was so much fun we are still laughing a hour later. We will be doing them outside now. 10/10 would do it again inside though. Worth it. ... show more

  • Fun and easy to use
Style: Extreme Geyser Tube
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.

  • Why did I wait?
