Dry ice between spoons

You will need:

  • Dry ice pellets
  • 2 metal spoons
  • Adult help



  1. Place a pellet of dry ice on a spoon.
  2. Place another spoon on top of the other spoon, resting on top of the dry ice pellet.
  3. Gently squeeze the two spoons together as if they were BBQ tongs.
  4. Wit the right pressure they should begin to vibrate and squeal!

What is going on?

Dry ice sublimates, meaning it changes from a solid to a gas without the liquid phase. Trapping the dry ice between two spoons creates a squealing sound due to the gas pushing against the spoons as it expands. The faster the spoons vibrate the higher the pitch.
