Features:

  • Use this simple science tool to create a bubbling soda geyser that can reach up to 30 feet into the air.
  • Experiment with one of the most viewed science experiments online. Truly an internet sensation on a blister card.
  • Discover the power of carbonation inside of soda. Learn why diet soda works better than regular soda, and why MENTOS are the best candy to reach new geyser heights.
  • What is S.T.E.M.? STEM stands for Science, Technology, Engineering, and Math, which constitutes many of the areas educators look to cover for science based activities. We are proud to say that his kit has a strong focus on STEM.
  • The Amazing Science line of products has been designed to peak kid's curiosity for the world around them. These kits encourage kids to wonder, discover and explore in a way that will get the science to the dinner table. Our goal is to teach kids how to be amazing as they show their friends and family what they’ve learned. Real Science…Real Learning!
Fun for the kids!

Fun activity for the kids. The Mentos that come with the tube were stale and didn't produce the same height as fresh/new Mentos. Use diet name brand soda for the best/tallest geysers.

Great for the Mentos and Soda experiment

I always do this at my son’s birthday parties and this made it so much better because we didn’t have any issues losing the mentos! Wish I would’ve found it sooner!

All the fun of Mentos and Diet Coke

All the fun of Mentos and Diet Coke, but with a little control and much easier. The kids had a blast with this. There are also directions on the back and a brief explanation of the science behind it. I'll be using this as a science experiment again in the future, just for the fun of it.

So much fun!

We got a few of these for my son's science birthday party. It was so much fun to try different mentos and soda combinations. These tubes made it easy to get the mentos in the coke and the kids absolutely loved it. What a fun way to end our slate of experiments!

This has added loads of fun to our household

This has added loads of fun to our household. My son has recently become a science fanatic and he is loving these new tools to help him make his science experiences successful. Of course I am wasting a 2 liter of diet coke every time we use it but for all of the laughs and giggles from him it is well worth it. Tons of fun for us all

too much fun!

a little pricey but soooo worth it. I had to show my 10 year old the joys of Mentos and diet cola. Since diet doesn't have sugar it wont make your sidewalk all sticky or become a giant ant magnet. I suggest that this be sold in pairs or a 6 pack - get all the kids in the area in on it. One note of warning - sparkling water with food coloring is cooler BUT just make sure that it's your kid in old cloths on the trigger here. Or, choose the kid of the neighbor you don't like and don't mind not talking to for the next few months. Enjoy!

work great but buy more mentos

you'd think you could do a lot with one thing of mentos but when you figure out that you need like 3 or more for each pop bottle.. just be prepared. otherwise - works as intended!

Totally simple, great gadget!

My 10 year old daughter had a science fair project to do. She decided to do the quintessential Mentos and soda explosion. Daddy agreed to help with the messy part outside. Those geysers are huge! Lol! I bought this item to help teach my daughter about science experiment controls. It made her happy because it made the project seem more professional. The candy dropper worked exactly as it is described. We were well pleased. She was able to insert the candy, slide the lever and run. The suggestions for turning the geyser from just a trick into a science fair experiment were included on the Steve Spangler website in a well done way with explanations and videos, etc. That was much appreciated!

Works well, take care in activation.

This works as advertised - however be careful when pulling the string and pin. You have to pull the string so the pin comes straight out - very little up or down movement or the bottle will fall over. If you have a child pull the string (and they will want to!) make sure they pull it straight out. My 11-year-old daughter tried to pull it from an angle - then she panicked to get away as the bottle fell over and she ended up tripping and hurting her hand a little - this is NO FAULT of the product, but be aware that children are thinking more of the result than the correct method of pulling the string. The bottle falling over doesn't make as exciting a geyser when put back upright, and extra bottles of coke aren't a dime a dozen, so make sure the child knows how to pull the string properly. My tube works, but I don't really want to bang the tube around too much - I'm unsure how sturdy it is. I wouldn't put it in a bag where it can rattle around. ADDING: If you're taking these to a demonstration and leave these in a hot car, let them cool down (or cool them) first. The bottoms will expand a little bit wider than the bottle opening, making putting them into the bottle possible, but a fight.

This is such a fun science experiment to do with children

This is such a fun science experiment to do with children. I love how easy this contraption is for even preschoolers to use. They love pulling the red release and knocking the mentos down and running away.
