How to Make Curly Fish:
Step 1: Cut a simple fish shape from a sheet of celluloid. Your fish should be about four inches long and one inch wide at the widest part of its body and one inch wide from tip to tip of its V-shaped tail.
Step 2: Drop the fish into a bowl of water.
Step 3: Tell a friend that your fish is so lifelike that if someone picks it up out of the water, it will curl up. When your friend picks up the fish from the water and puts it in his or her hand, probably nothing will happen. But if you rub your two hands together vigorously and then ask your friend to put the fish flat on your open hand, the fish will curl its head and tail together within a few seconds.
