Rainbow Glasses

Neon strip cardboard spectacles with diffraction gratings as the lenses. You can see the regular world, but all light sources and bright objects appear in multiple rainbow hued images. The effect is a little as though the whole world were a giant hologram. Great stocking stuffer or birthday party item for grade school ages.

Brain Benders

Warning!  WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.

A box of illusions: make big objects look small, and small objects look big; change black and white into color; turn drawings into old-style movies - just for starters. You get a motorized zoetrope/spinner with discs and strips, and a really amazing "altered perspective chamber," along with directions for a dozen optical activities. It's really mind-bending - but don't forget to buy (2) "AA" batteries for the zoetrope. Spinning it by hand just doesn't work as well! For ages 8 to adult.

Break Your Own Geodes

Warning!  WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.

Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

Clever Idea #763

This idea is for the birds. Literally. A green/black plastic perch, dish, and dispenser that you can screw onto an inverted plastic pop bottle to convert it into a bird feeder. Obviously, the bottle should have been emptied of pop and filled with seed. One of those "100 things to do with old coat hangers" ideas that really works!! Complete with instructions and bail to hang the completed feeder. Please note: this feeder will not attach properly to the new Coca-Cola low-profile bottles.

This excellent 38-1/2" x 26-3/4" poster of the Periodic Table lists the elemental information about Gd and 117 other elements, and includes mini-biographies of (7) scientists. The full-color poster is not laminated, but is a good quality coated paper, and a fascinating addition to any classroom.
