/*******************************************************************************************************/

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

/*******************************************************************************************************/

====Variations====
  * 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.

/*******************************************************************************************************/

====Safety Precautions====
  * 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.

/*******************************************************************************************************/

====Questions to Consider====
  * 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?
