Spud Launcher
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
A plastic pistol shaped toy that shoots slugs of raw potato. Push the barrel into a potato, break off the slug, aim and shoot up to fifty feet. Loads of fun, environmentally harmless, and about as safe as any "projectile" toy can be!! Pulls apart for cleaning. For kids ages 5 and up.

Thermal Sensor
Heat switch that is normally open below 135° F and closes at higher temperature. Imagination is the limit here. We don't have formal electrical ratings but believe it can handle about 2 Amps @ 120 VAC. It can be used (perhaps with a relay) to trigger a fire alarm when mounted near a furnace, in a garage, or in an attic. How about using it to shut off electronics or motors when overheating occurs? Or to activate a fan for cooling? Use it to record how long the furnace is on to rate its efficiency. 5/8" dia x 3/8" sensor head with (2) 1/4" x 1-5/8" long fixed leads.

Lazy Scott Bearings
Never seemed fair to nail the "lazy" tag so permanently on the "Susans" but that probably has no "bearing" on the issue. Also called turntable bearings, they are the square, flat ball bearing devices YOU bolt between two flat objects to achieve rotation. Like that spinning center section of a Chinese restaurant table. We had these in surplus once and they were quite popular. To our chagrin, we discovered they could be bought commercially for the same price. So we did. The 4" version is rated for a 300lb. load, the 6" for 500lbs., and the 12" (round) for 1000lbs.

Pull, Pull, Pull Your Boat
A couple of pulleys just ready to be combined into the block and tackle you need for tiny jobs, like trimming your bonsai trees or hauling your model boat out of the pond. Get blocks with (1) or (2) sheaves and rig up whatever you need. Each block has an aluminum frame about 3–1/2” long with “S” hooks on each end. The sheaves, or wheels are about 2” dia x 1/4” wide, with a “V” groove that looks perfect to handle 1/8” or smaller Venetian blind cord. These dudes are perfect for demonstrating mechanical advantage in the physics lab!! But not for heavy lifting.

Hot Hot!!
This flash heating element out of a coffee maker really heats in a hurry!! It is designed only for use with a regulating heat switch (not included) and will melt itself in less than a minute if turned on un regulated with no water or other contents. It draws 8 amps @ 120 VAC max. 2" dia x 2-1/2" tall, OA. It holds about 1 oz. and has (2) spade terminals. A wonderful item when used correctly.

Right Angle Driver
Direct that power right where you want it. Inside the metal box are a couple of gears and shafts, what counts, though, is the way it lets you turn a shaft at a 90° angle, with no loss of power. 1/4" splined shaft couplings, male at one end and female at the other. 2" x 1-3/4" x 1" thick overall.

Kaboom
One of our truly unusual treasures. It's a used 28 VDC single-pole/single-throw toggle switch, possibly military surplus. A sensor mounted on it is labeled Oxygen Warning Switch. We think that means that it switches off in the presence of pure oxygen, the better to keep from blowing something to kingdom come with an errant spark. Overall, it's 3-1/2" x 1-1/2" x 1", not counting the 3/4" toggle. The 3-pole sensor itself is under a black-painted aluminum cover 1-1/2" high x 7/8" dia. (3) leads, (3) holes in its right-angle mounting bracket. We're just not sure what it is that would be blown up if it weren't there.

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.

Cinema Vérité
Hey, Coppoletta! Add realism to your home flicks with a Hollywood director's slate board. This 8" x 7" version is wood, painted black with white lettering. The traditional striped arm on top cracks down on the palimpsest where you chalk in the Production, Director, Camera, Date, Scene and Take. Very Vérité
