Qualatex 79696 Lime Green Latex Balloons, 260Q, Lime Green, Pack of 100

A fascinating optical illusion device and just the sort of scientific curiosity we love. Any item of a suitable size placed in the base appears to float above it totally unsuspended. Viewed from the right angle it is so effective that the impulse to reach out and touch it is almost irresistible. Cleverly packaged to demonstrate the effect - the red pompom always rolls to the center of the parabolic mirrors, that are the key to the secret.
