====Procedure====  
  - Fill a plastic container halfway with warm water.
  - Attach a rubber tube to the side near the top of the jar so fog can escape through it.
  - Drop several pieces of dry ice into the jar and loosely cover the top with a lid to direct fog through the tubing.
  - Mix dish soap with a small amount of water in a container to make bubble solution.
  - Dip the free end of the tubing (or funnel attachment) into the bubble solution to coat it.
  - Cover the jar with the lid while lifting the tubing out of the solution to form a fog-filled bubble.
  - Gently release the bubble and watch it fall, bounce, or burst with a puff of fog.

====Variations====
  * Bounce bubbles on different fabrics to see which work best (towels, knit gloves, shirts).
  * Make giant Boo Bubbles using a larger bottle and hose dipped into bubble solution spread across a table.
  * Play “volleyball” with bubbles by bouncing them between two people wearing gloves.

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

====Safety Precautions====
  * Always use adult supervision when handling dry ice.
  * Wear heavy gloves when touching dry ice to avoid severe burns.
  * Wear safety goggles to protect against shards when breaking dry ice.
  * Never seal dry ice in an airtight container - it can explode from gas buildup.
  * Perform in a well ventilated area.
  * Never put dry ice in your mouth or store it in a freezer.
  * Keep dry ice in a ventilated container such as a Styrofoam cooler with a loose lid.

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

====Questions to Consider====
  * Why are fog-filled bubbles heavier than regular bubbles?
  * Why do the bubbles bounce on some fabrics but not others?
  * How does sublimation make dry ice turn directly into gas instead of liquid?
