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.

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 nice pulley 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 this block with (1) sheave 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.

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.

Tough Models
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
A construction-grade Cindy Crawford? You wish. No, just difficult (and definitely not for toddlers) models/puzzles. But if you've got a building-set whiz-bang in the back seat, these 50-piece, 3-D puzzles are demanding and rewarding to assemble, plus they come in ultra-thin packages for traveling. The highly detailed, colorful pieces punch out of a couple of 6" x 4-1/2" credit-card-weight plastic sheets but assemble to sizes ranging from 4-3/4" x 3-1/2" to 8-1/2" x 4-1/2". We'll pick (2) different ones from a selection of heavy construction vehicles and nasty robo-animals (think "Rhinotank" and "Wolfborg").

MiniMultiMeter
Our pocket-sized multimeter measures a tiny 3-5/8" x 1-3/4" x 1" thick, with a 3-1/2 digit display on a 1-1/4" x 9/16" LCD screen. Will measure up to 500VAC, 100VDC, current from 200uA up to 10A, resistance up to 2000K ohms, and will also test diodes and transistors. Comes with (2) 24" test leads and a battery to power it. Teeny price to match its size. Great for science fair projects.

Step On It
Perfect for hands-on hobbyists. Foot-pedal speed controls free up your paws to do the real work. This one's for 120VAC devices, and ideal for machines using approx 200W or less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.
