Let's break it down: No, this isn't a mini nuclear explosion, this is what happens when the fun of bubbles intersects with the creepy-yet-cool nature of dry ice. Dry ice, which can be bought at nearly any grocery store, is frozen carbon dioxide. When a chunk of this ice is put into water, it produces a great deal of steam. By adding some dish soap to the water before adding the dry ice, you can make a bubble that takes up the entire area of the bowl. When the bubble pops, it has a hauntingly beautiful appearance as the steam is freed.
