Soap bubble pop it
If you freeze a few bubbles, they’ll make a Pop It!
Attention! All experiments are performed by professionals. Do not attempt.
Dry ice is solid carbon dioxide at temperatures below –78°C (–108°F). It quickly cools the baking dish by filling it with cold carbon dioxide. Air is about 1.5 times lighter than carbon dioxide, so bubbles inflated with air will levitate over the dish. However, if you inflate them with carbon dioxide, they sink into the baking dish. Soap bubbles contain water, which has a freezing point of 0°C (32°F). As a result, the water freezes, strengthening the shells of the bubbles – this makes for a great Pop It!
