2 Dry ice between spoons science experiment - dry ice being squeezed between two spoons

Place another spoon on top of the other spoon, resting on top of the dry ice pellet.

Gently squeeze the two spoons together as if they were BBQ tongs.

With the right pressure they should begin to vibrate and squeal!
