Budding meteorologists will love this Weather Science kit from Green Science. Includes experiments with lightning, static electricity, cloud-making, greenhouse effect, water cycles and acid rain. Comes with thermometers and holders, a balloon, seed tray, pH paper, and sundry plastic instruments. You add a few common household items.
Our first steel pot from the Bulgarian army, this pre-worn beauty has very high-quality leather-covered foam padding inside. Adjusts to fit non-Bulgarian noggins and has an integral adjustable neck strap. Shape is sort-of U.S. Army-ish with a slight flare at the slightly extended ear protection. Might have some tiny evidence of rust here and there.
This 12VDC tin-can stepper motor from the Nippon Pulse Motor Co. is a uni-polar 2-phase with 50 Ohm coils drawing 240mA per phase. Moves 48 steps/revolution with a 1/10 gear head at the output. Measures 1-5/8" dia x 1-1/2" on a 1-11/16" square mounting with 1/8" mounting holes. The offset flattened shaft is 1/2" long x 3/16" dia. Has (6) leads with a Molex connector. Part #PF42-48.
These translucent silicone O-rings are 3/32" thick and measure 4" dia. Nice belts for science-project motors and even nicer for our slingshot needs. Crafters will see jewelry material that the metal-detectors won't care about.
Frees up your hands while you examine whatever you’re examining. The approx 2-1/2" dia acrylic lens is 2X (ignore the surplussing 2.5X on box) and is mounted in a black fold-out frame with a pair of white LEDs underneath the lens for your examining pleasure. Measures 4-1/4” long and includes 2 replaceable AG7 batteries.
Orienteering fans will love this nylon camo map case. Opens to 27" x 19" with a clear vinyl window on one side and a hook-n-loop flapped pouch measuring 8-1/2" x 5-1/4" x 1-1/4 with (4) pen sleeves on the other. Folds up to 13-3/4” x 6-1/4” x 1-1/4” with a lanyard clip for carrying. Surplus factor: the clear vinyl is smudged with lines of what look like blue lettering that migrated onto it. Non-orienteerers will find it handy for travel storage for small items.
Actual shells from coconuts that once hung on real trees. Really. De-fibered, so they feel fake, but trust us. Average approx 4-1/2” long x 3-1/4” wide x 1-7/8” deep. Indispensable for Monty Python reenacters, Foley artists, conga bands, South Pacific performances, backyard luaus and a plethora of Polynesian practices. Our each is (10) half-shells.
Imagine the issue of a marriage between a party light and weed whacker. The handle is shaped like an 8” long squid with a spinning diamond head that flashes red, blue, green and yellow while (4) 5” long strands light up while they spin around and morph through different patterns (at 32 rpm, as if that mattered). Three “AAA” batteries included so you can show the mail carrier how it works as soon as you get it. Bonus: set it down and it sort of spin-walks around a tabletop.
The Princess pack of craft pieces, from Kaizen. You get (20) packs of a whole bunch each (10 to 20, depending on size) of shiny or sparkly butterflies, hearts and stars, all approx 3/8” to 3/4” in pretty princessy colors. They all have teensy holes for stringing them along, or you could just scatter them on tabletops during parties and spend the next three years finding them on the floor.
