Pieces of dry ice are put inside a balloon causing it to inflate.

1. Put on gloves to handle dry ice safely.
2. Hold open the neck of a balloon with your fingers or use a funnel.
3. Place a few pellets or small pieces of dry ice into the balloon.
4. Tie the balloon tightly to trap the dry ice inside.
5. Set the balloon on a surface and watch as it inflates from the sublimating dry ice.

• Experiment with crushing dry ice into smaller pieces to see if inflation is faster.
• Use a latex glove instead of a balloon.
• Use a sandwich bag with a small amount of water and dry ice, then seal it and watch it pop.

• Always wear gloves when handling dry ice to prevent frostbite.
• Do not hold the balloon in your hand while it inflates - set it on a surface.
• Never put dry ice in your mouth.
• Keep dry ice out of reach of children and pets.
• Do not enclose dry ice in rigid airtight containers, as pressure buildup can cause explosions.

• Why does dry ice turn directly from a solid into a gas instead of melting into liquid?
• Why does frost form on the outside of the balloon?
• Why does a dry ice balloon sink instead of floating like a helium balloon?
