Another oldie but goodie. 5" high evacuated clear glass bulb mounted in a black 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.

No more springing forward or falling back, ever, with this talking atomic alarm clock. It sets itself from the atomic clock in Ft. Collins, Colorado, so you can forget it even before you set it. Push the buttons on top to hear the time, light it up, or snooze. The retro analog white face is 3-3/4" dia with glow-in-the-dark hands. Has settings for time zone, alarm, daylight savings time and manual time adjustment. Resets automatically every evening, or push the "wave" button to refresh. Measures 5" tall x 4-1/2" wide x 3+" thick overall. We have it because, while the clock is brand new, the box may have been beaten up a little. Requires 2 "C" batteries (Not included).

Well, if you had a crystal ball, you'd be able to see that there's a crystal ball in your future, and you'd know not to pass up this very, very nice glass gazing ball. It's 4-1/4" dia (and heavy) and comes with a footed dark-wood stand that spins smoothly. The stand is just over 3" dia. Together, the ball and stand are 6-1/4" tall. Comes in a presentation and storage box. The perfect accessory for your next fortune-telling gig.

Bigger than a baseball across the top, this is one ginormous jewel. You pick a clear or deep-translucent-blue, 24% lead crystal, cut-glass gem. It’s 3-1/8” dia at the top, tapering to point 2-1/8” deep. Could be mounted in a stunning, but really, really, really big engagement ring.

Newtonian demonstrator for science teachers. Mindless play for the rest of us. These are shiny, nicely balanced, high-performance examples of the classic Newton’s Cradle – a ball on one end of a row of (5) suspended, barely touching balls swings into the others, and the ball at the opposite end reacts to the collision. The 11/16” dia balls in the small version (all-metal frame 6-1/2" high x 4" x 4-1/4") will collide about 30 times. The 7/8” dia balls in the large version (metal frame 5-1/4" high x 4" x 6", with a wooden base) will collide about 100 times. Awesome. Even more awesome that we paid someone to count the bounces just for you! (Unpacking note: Less awesome if you just yank it out by the suspension lines and pull a couple of balls loose. Be gentle.)

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.

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

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

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.
