Big Dry Ice Bubble

A bowl of water with dry ice is sealed with a soapy film that stretches into a giant bubble. As fog from the dry ice fills the bubble, it grows larger until it bursts.

1. Place a piece of dry ice into a large bowl and pour in some water.
2. Mix dish soap with water to create a bubble solution.
3. Soak a strip of cloth in the soapy solution.
4. Wipe the soapy cloth around the rim of the bowl.
5. Drag the cloth across the top of the bowl to create a soap film sealing the opening.
6. Step back and watch the bubble inflate with fog until it pops.

• Try using a smaller cup or a much larger bowl to change bubble size.
• Add food coloring to the bubble solution for a visual effect.
• Use different soap-to-water ratios to see how it affects bubble growth.

• Only adults should handle dry ice.
• Always wear heat resistant gloves when touching dry ice to avoid skin burns.
• Work in a well-ventilated space to prevent carbon dioxide buildup.
• Students must not remove dry ice from the demonstration area.

• Why does dry ice skip the liquid phase and turn directly into gas?
• How does the soap film hold the gas inside the bubble?
• How does temperature affect the speed at which dry ice sublimates?
