2" flywheel in well made metal frame. The trick is the same as it has been for 100 years. Wind the string through the spindle, pull it firmly to set the flywheel spinning, and perform effortless balancing magic on pencil tips, string tightropes, and the like. We tend to forget that bicycles and aircraft navigation both rely heavily on gyroscopic principles. It's never too early to tell the kids. Besides, it's fun.

More fun for the easily amused! A very stylish 3-1/2" x 5-1/4" clear acrylic panel, less that 1/2" thick has two flattened hourglass chambers within it. Both have non-toxic fluids and suspended in one are black grains that are heavier than the liquid. In the other are colored grains that are lighter. Flip the works from one black plastic end to the other and the grains slowly do their things, black down, colored up, over maybe a five minute period. Very soothing. We'll pick your color from neon red, orange, chartreuse and magenta.

Just leave bread in a damp place. Or buy this stuff and make casts of solid objects, anything from faces and fingers to celery and crucifixes, with quick-setting Instamold. (We'll sell you 10 oz. of the Instamold compound, but you provide the water to mix it with.) Then fill the molds you've made with plaster, wax, or Permastone-yes, we sell Permastone too. It's an extremely strong casting medium with a clean white hue when set, waterproof and scratch resistant. Each can we sell has 1-3/4 lbs. of Permastone, to be mixed with water.

It's nice to know that some things don't change. One is the Jacob's Ladder. Still made with (6) slabs of wood, each about 2" x 2" x 1/2", each a bright combination of colors, and all connected by a contrasting ribbon. Hold one end up and let the string of slabs dangle. When you flop the top block end for end, each lower slab in turn will flop end for end. Fascinating. Particularly if you are about 5 to 9 years old.

Black and white sand in a viscous colored fluid. The sand and fluid are between 5-1/2" wide x 3-1/2" high panes of glass, framed on a gimbaled stand. Flip the panel and watch the sand swirl and eddy into endlessly new pictures of dunes, drifts, mountains or moonscapes, depending on your imagination and the pattern they form. The mix of black and white creates a definite third dimension to the images. They come in assorted colored plastic frames (our choice) and are pretty neat, as these things go.

Spin this spindle and watch it turn in perpetuity!! Well, for a long time anyway. Inside the 5-1/2" long colored plastic spindle are magnets which are repelled by magnets in the 5" x 3" black plastic base. The variously colored spindle floats in the air above the base thus virtually free of normal friction. It also has red lights to light up its way as it spins, giving it almost a strobing effect. Nifty desk toy named "Revolution".

A "One gizmo does all" marvel. It really works as a binocular, magnifier/linen tester, and has a signaling mirror, and compass all in a roughly 1-1/2" sq x 3-3/4" long package. The bino eyepieces and objectives fold against the body with the objectives doubling as magnifiers when used alone. The signaling mirror makes a good examining table for bugs and seeds etc and is conveniently located under one of the lenses. It should make a good "going off to camp" gift!

Absolutely magnificent magnet!! Very strong - we estimate it has a 35 lb. pull - neodymium-iron-boron (rare earth) that is only about 3/4” x 1-1/8” x 7/16” thick. It is actually trapezoidal, so the 1-1/8” dimension slants from 1” to 1-1/4”. They are pretty clean take-outs, painted silver, white or black, and may have some very small chips. Be careful!! These guys will murder a computer or audio/video tape. A pair will leap into a deadly embrace from over 6” apart and may knock chips off themselves from the force of their impact!! A single magnet holds (4) of our catalogs (11 oz, 5/16” thick) to the side of a steel file cabinet. We cannot say too much in favor of this magnet!!

Finish it off with das periscope. Perfect for a blue-plastic submarine, our blue-plastic periscope will let you see the destroyers following your bubbles, or, if you're stuck on land, let you look around corners. Our visual aid is 1-3/8" dia, telescopes from 14" long to 10", has a clutch to secure the length and a 1" dia port to look through. Handy for reverse snorkeling, too. (Just think about it, OK?)

Think of it as a shortcut to learning perspective. This clever 50-sheet pad of white, 7" x 4-1/2" paper has a fine red and blue grid pattern that shows your drawing and doodling in 3-D when you wear the included 3-D glasses. It's our candidate for the why-didn't-I-think-of-that award this year.
