Dry ice is different from regular ice. Rather than being frozen water, dry ice is actually frozen carbon dioxide. In this video, some of the interesting properties of dry ice are exploited on camera.
Because of its extreme cold and properties, it can be dangerous to handle. Eye and hand protection are required when handling dry ice to protect your body from harm.
You'll see that because oxygen is lighter than carbon dioxide, oxygen bubbles do an interesting dance atop of the carbon dioxide bath. You'll also be amazed to see what happens when a warm coin gets placed inside of a brick of super cold dry ice.
It's recommended you don't try this at home without first taking all safety precautions to protect yourself.
