Actually a very thin piece of red cellophane in the shape of a 3.5-inch long fish, this amazing innovation twists and curls when placed in the palm of your hand. It seems to move magically, different for different people. The truth is, it is sensitive to the moisture of your hand. An old favorite of demonstrators. Ask your students to explain what makes the fish move. Includes explanation.

Instant Snow Polymer

When this granular white powder is added to water, it instantly expands to 40 times its original volume, producing a snow-like material.

Large Gro-Beast Alligator

These growing alligator/reptiles start at about 3 inches long and grow to over a foot long when placed in water!

Sodium Polyacrylate (Diaper Polymer)

The super-absorbent polymer found in disposable baby diapers. Also used in many "disappearing water" magic tricks.

Ultraviolet Detecting Beads

Change color when exposed to ultraviolet light from the Sun or other UV source.
