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.

25813 HEAT SWITCH, 135DEG F |
Resistive element insulated and wrapped in soft, flexible (fiberglass) jacket. The wrapped section is about 27 inches long and about 3/16" in diameter. Each end has a 4 inch insulated lead, but one end is a single strand solid wire and the other is a seven strand braid. We haven't any idea where the marriage takes place! Anyway, they're rated at 90 watts. Plug 'em into 110 VAC and the thing heats up to the point that it's quite hot to the touch - too hot to hold onto. Wrap it around whatever it is that you need to keep warm and make your own heating systems. Make yourself a coil and you can probably keep your coffee pot hot. Or operate it at 12 volts as a telescope dew chaser. You'll notice some smoke when you plug it in the first time, but this won't happen once it's burned in. Happy heating by Hot Watt. Melanie, Tory, and Donna all want one!

1490 HEATING ROPE |
The heating element from a common household iron. Shaped like the base of an iron, 5-3/4" long x 3-3/8" wide, with an open 3-1/4" x 1"center. The element wire is embedded in ceramic, but is still a real fire hazard and will glow red at max temperature. It runs on 120 VAC and has (3) threaded hook-up terminals: the center is neutral, the two sides draw 200 and 400 watts or use both for 600 watts. Surface temperatures: 1250°F with 600 watts (5 amps), 1000°F with 400 watts (3 amps), and 700°F with 200 watts (1.5 amps). For safety's sake, please use it with a heat switch.

These supposedly began life as paintball ammo holders. We don't know what you've got in mind for them now, but they're exactly the right size to hold our fountain pen, the one that once leaked on an airplane and ruined a perfectly good shirt, the inside of a suit, and our whole day. But they'll also hold a cigar, double as a test tube, store small amounts of almost anything. Translucent white-plastic round-bottomed tubes, 11/16" dia x 6-1/4" long with a snap-in cap and, most of them, a little flash around the bottom. They hold 30 ml, which is almost exactly one shot. Probably a coincidence.

Omelets for all your friends! If this 35" long balloon whisk was big enough for the German army it's big enough for you. Verstehen sie? The business end has 12-1/2" long x 6" dia wire loops on a 1-15/16" dia wooden handle. Just don't tell der Kommandant you're using it to make barbecue sauce in the kiddie pool.

It's the world's largest rubber suction cup, made for the military for (honest) plugging holes in ships until the guys with the welding torches can take over. In 3/8" thick yellow rubber, it's 24" dia x 5" tall at the center, with a molded bracket at the top. They've got some schmutz on 'em, so a soapy brush is in order, but clean them up and you've got very wind-proof garbage can lids; perfect boat bumpers; gym-floor tie-downs; plugs for 23" drains; the biggest dent-pullers in the universe; a puncture repair kit for your yacht; or the makings of a serious practical joke.
