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

## Questions & Answers

**Q: Can you attach a string to the cap or pull pin, so kids can sit out of the way and pull the string?**
A: Absolutely! We recommend a thin sting to go around the pull pin and a light pull motion that won't break the geyser. Try it in your hands a couple of times before attaching the geyser to a bottle.

**Q: Does this only make one geyser or more than one? -- like can I keep re-using it as long as I buy new coke and new mentos?**
A: Only one geyser. Yes, you can use it a lot of times. There is nothing to break by time, just be gentle when you putting it on bottle-you can throw mentos to coke by accident before you tighten it

**Q: Can I use carbonated soda water?**
A: Haven't seen if it will work with anything other than soda, but it should work the same.... Give it a try.

**Q: I am thinking about ordering a few of these for an experiment with my students. Do you lose the tips when it explodes? Are the tips necessary?**
A: The tips stay on. You can order the one with different tips its even more fun.my 8 yr old had a blast!  Some tips shoot higher some have More then one stream.

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.
