Disappearing-Reappearing Rabbit Trick: A New Twist to an Old Liquid Nitrogen Demonstration.
Haub, Elaine K.
Journal of Chemical Education, v78 n1 p46 Jan 2001
Demonstrations using liquid nitrogen are very common in chemistry courses and chemistry outreach programs, and the shrinking of a balloon when cooled and its subsequent "re-inflation" upon warming is a crowd pleaser. Uses a rabbit balloon which "disappears" as it is lowered into the hat and "reappears" when it is removed from the hat. (ASK)
