This is a dry ice project that kids should have a lot of fun with! In addition to having fun, they'll also learn the science behind dry ice. My son had a lot of fun playing around with it - but you need to be extremely careful so you and the kids don't get hurt. Dry ice is frozen carbon dioxide - the same gas we exhale out when breathing. It's also used to carbonate drinks and make soda. You'll need a nice pair of thick insulated gloves for handling the dry ice and you can also use tongs. When dry ice "melts," (it doesn't technically melt - but you know what I mean) rather than becoming a liquid, it changes directly from a solid to a gas. The process is called sublimation - and you can see it happen!

Warning: Dry ice is dangerously cold and you should not let your skin or body come in direct contact with it. It's also a good idea to be in a well-ventilated area - even better, you can do it outside. You can get frost bite if you're not careful. When buying it, do not place it in an airtight enclosed container - leave it open a crack. It's also a good idea to wear safety goggles. Please be safe and exercise caution with this - especially doing this with the kids. Have fun and do this at your own risk! For more dry ice safety information, you can read about it here.

Here is a super short video demonstration of it in action! This one in the video was a small bubble - but it was still cool to see it pop!
