## 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.
