This is a super fun activity to do with your grandkids. It’s very interactive and you can teach them about dry ice. Did you know that dry ice is 110 degrees below zero. Dry ice is not a frozen liquid, its Carbon Dioxide that is compressed and frozen. When dry ice melts, it tuns back into gas, not a liquid.
Give it a try and you’ll be the cool grandpa.
