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.

Rattlesnake Eggs
Or singing suppositories. The pair is very magnetic, whatever they are. The 1-3/4" long oblate spheroids look like highly polished black hematites. Hold them an inch apart in your palm, toss 'em into the air and listen to them make a sound like the cyber-crickets. Or an electrocuted chicken. The manufacturer suggests keeping these mega-magnets away from computers, pacemakers, TV sets and credit cards.

The Dragon Flies Tonight
And it's a larger-than-life R/C dragonfly! About triple the size of the largest dragonfly on record, but 10 times bigger than the ones you see around the neighborhood pond. Our radio-controlled buzzer has a 16-1/2" wire-and-cellophane wingspan and a 13" long styrofoam" body, and flies by flapping his big wings. He's stabilized by a small tail rotor (which you won't find on the real thing). The controller runs on (6) "AA" batteries (not included) which also charge the futuristic dragonfly's internal battery. Wings and rotor have continuous variable speed. Range is approx 50 feet and there is a trimmer dial to keep him flying straight. Charges in 20 minutes for 7 minutes of flying time.
