Dry ice, actually solid CO2, can be obtained locally at:

  • Food 4 Less - At the entrance. As of February 2008, it was $0.95/lb.
  • Save-mart - At the western entrance. As of August 2016, it was $1.99/lb.
  • Campus - But only if you work in a lab.

Don't touch dry ice with your bare skin; it burns.

Dry ice may be very useful for:

  • Spooky effects on Halloween. Place some dry ice and water in a cauldron and eerie clouds of "steam" will bellow forth. When the water gets too cold, it will stop as the dry ice becomes encased in solid water.
  • Keeping things like drinks cold.
  • Making unusual noises by forcefully pressing the convex side of a spoon onto the surface of the ice.
  • Making cold things like ice cream. Put the dry ice on top of the ice cream, not below, ideally with some thin cardboard in between. A little goes a long way — too much, and your ice cream will be rock hard.
  • Making small explosions by placing some dry ice and water in a sealed soda bottle. NOTE: Dangerous and a Felony under 12301(a)(6).
    • If you ever wish to do this, use thin plastic coke bottles rather than glass or thicker plastics which may form projectile shards. ~DavidPoole
  • Using a rotary evaporator.. but only if you are working in a lab.
