Perpetual Motion
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".

Original Slinky(r)
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Does anyone need to be told what a Slinky(tm) toy is?? Okay, it is a very slack spring, 2-7/8" dia x 2-1/2" long, compressed. It will stretch out to about 5 or 6 feet long without deforming. That's the boring part. The interesting part is that it "follows" itself. Slosh it from hand to hand. Put in on the top step of stairs, flip the end down a step, and watch it walk down stairs, or down an incline. Believe us, no childhood (or adulthood) is complete without an original stainless steel Slinky(tm). It was hard for us to find it, but we are glad we did. You should be too.

Elemental Information
Holy Gadolinium, Batman, who discovered this Gd element? We're not sure, but he's close to our hearts, since Gd is a magnetic metal of the rare-earth group, and you know how we love rare earth magnets. 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.

For Mature Adults
We won't tell anyone. We know you're a mature adult who's seen a lot over the years. You've seen so much that you've worn out those old eyes of yours. We won't tell anyone that now you need a 7-1/2" x 5-7/8" x 7/8" OA calculator with a big 8-digit 3" x 3/4" adjustable display. With big, high-contrast buttons. With all the standard memory, square root functions, etc., that you've forgotten how to do without a little help. And its battery operated so you don't even have to remember to use it in the sun. Ain't maturity grand?

Peltier Heat Pump
High tech comes to Am Sci & Surp!! It is here in the form of a Peltier junction, a thermo-electric device that translates electric power into heat, and perversely, into cool. Apply current @ 3-12 VDC to the gizmo and it extracts thermal energy from one face, thereby cooling it. The heat is dumped onto the other face, thereby heating it. Please note: you must use a heat sink on the hot side or the junction will fry itself, since it can quickly create a 65° C temperature differential in a no load situation. Stack two, or build a cascade to increase the thermal differential created. Or run it backwards. Apply heat or cold to the relevant face and produce a current. Amazing for science projects and experiments. Practical for coffee warmers, beer coolers and mini-refrigerator or warming oven applications. Comes with instructions. Large is 1-9/16" sq. x 3/16" thick.
