There is no better ways to learn science than doing your own experiments. Steve Spangler’s Boo Bubbles is a fun kit that lets you make your own dry ice smoke bubbles. To get started, simply fill the bubble generator with warm water and a few pieces of dry ice, drip the bubble blower in the solution and the rest is easy.
When the dry ice reacts with the water, smoke filled bubbles come out of the bubble generator. You can control the flow of the gas to make any size bubble.
