Sign In/Up! (It's Worth It!)
Radiometer
Another oldie but goodie. 5" high evacuated clear glass stand 3" in diameter at the top. A four bladed vane is balanced on a needle inside the sphere. Because opposite surfaces of the vanes are black and white, incident radiant energy is absorbed or reflected to a different degree. The result is a spinning vane. The brighter the light, the faster it spins. Simple, but compelling. Brief explanatory instruction sheet included.

Mirage Maker
Absolutely incredible device! The Mirage®, a precision optical instrument, creates three-dimensional images of objects of your choice where there is nothing. Drop pennies, keys or similar small objects (your sister won't fit) into the 2-3/8" dia opening of this 9" dia x 3" high flying-saucer-shaped disc, and a perfect image of the object will appear floating above it. The image is so real friends will try to grasp it, but their fingers will close on thin air! Use it as a high-tech centerpiece with a flower as the object! A booklet (included) explains the magic. New coating provides protection for the mirror surfaces. Highly recommended. Made in the USA.

Perpetual Motion
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".

Slick
Fascinations® are fascinating! This smooth, 4" dia Fascinations globe has labeled silver land masses and dark blue seas. It hangs, suspended only by electromagnetic forces, inside an 8" tall matte-finish silver-colored C-frame. A gentle breeze or vibration, and it slowly rotates. No batteries to wear down -- it comes with a 6-ft power cord/adapter. An absolutely mesmerizing -- and educational -- desk toy.

Front!
Time was, these service bells were on every teacher's desk and the front desk of every hotel in the world. They're still a classically beautiful design, and they'll still bring folks running when you tap the little plunger on top. The chrome bell sits on a black enameled steel base and the whole thing is 2-3/4" dia x 1-7/8" tall.

Endless Time
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.

Moving Sand Art
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. Pretty neat, as these things go.

Blip Blop Color
Executive toy consisting of a translucent plastic container, roughly 4" wide 6-3/4" tall x3/4" thick mounted on a swivel on a stand. The container has (1) clear and (2) colored, translucent immiscible fluids. Flip the container on the swivel and an ever changing series of blips and blops of color drift slowly down from the top to the bottom while bubbles and steams of clear rise from bottom to top. A mix of colors results as the blobs appear singly or overlap: red and blue single colors also yield purple patterns. Fascinating.

This fine wood abacus is approximately 9-3/4" x 4-3/4", with (13) sets of (5) balls and (13) sets of (2). Computing speed is considerably slower than even an old 286, but then it's guaranteed to never need rebooting. Instructions included. Made in China, naturally.
