See psychedelic patterns the safe way! Press your hand on this 6" x 6" sheet of liquid crystal and leave a print of swirling colors that, like the mood ring of yore, you can use as a sign of your mood. The pattern will blend and fade in seconds as the crystals react to temperature. Tiny liquid crystals inside the film-like material react to heat by changing colors. As science, it demonstrates the way liquid crystal displays work. And you can cut it into pieces to incorporate into a science project. Or just leave it out for guests to play with when the party turns boring.

91582 LIQUID CRYSTAL SHEET |
Need to hold something to a round steel pole? Want to make a magnetic bulletin board? Or to cut some letters for a temporary sign on the side of your car? Relax, the answer is at hand. You need some flexible 12 x 12 rubberized magnetic sheets. The magnetic particles are embedded in a rubber-like material that is easily cut with a pair of scissors. Strong enough to cling firmly to a smooth metal surface or to hold light objects. Sheets are just over 1/32" thick and are self adhesive.

WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Another gem plucked from the A.S.&S. mirabilia. The shape and size of a hen egg, this opaque stone (or matte-finished glass - we're not sure which) is interesting in itself. Touched with a red penlight in a dark room, the entire egg becomes a brilliant ruby color. Blue light/blue egg, etc. Fun and fascinating, and with a little sleight of hand, a sure way to convince the plebeians that you have some mysterious metaphysical power.
