Tested Demonstrations
Disappearing-Reappearing Rabbit Trick: A New Twist to an Old Liquid Nitrogen Demonstration
Elaine K. Haub
Chemistry Department, Indiana University Southeast, New Albany, IN 47150
Cover
January 2001
Vol. 78 No. 1
p. 46
Abstract
Demonstrations using liquid nitrogen are very common in chemistry courses and chemistry outreach programs. The shrinking of a balloon when cooled and its subsequent "re-inflation" upon warming is a crowd pleaser. Audience members have been known to exclaim that this is chemistry magic. Toying with that idea has led to a new twist to this old demonstration. A magic hat with a suitable container inserted holds the liquid nitrogen. Instead of a regular balloon, I use a balloon animal in the shape of a rabbit. The rabbit "disappears" as it is lowered into the hat and "reappears" when it is removed from the hat.
