Hexagonal silicone. Whatever you like to call them. You definitely need a bunch of these translucent white, six-sided silicone discs. We've seen three sizes, but there could be more (that's surplus for ya.): 2-7/32", 2-9/16" and 3-11/16” across and all 1/16” thick. Probably from a gasket factory, but they’d make dandy vibration pads, non-slip feet, Hobbit hot pads, shot-glass coasters, earrings or very odd bouncy floor tiles. We'll pick a handful of assorted sizes for you.

This multi-use, all-purpose, tear-resistant, all-weather generally handy blue tarp is for covering up stuff. Measures 7 x 5 feet in .0085 thick plastic (polyethylene) with rust-proof aluminum grommets and a 1/16” poly rope inside the hem to give it extra stability. Also makes a nice lean-to or an ugly raincoat.

And people won't crash into you, because nothing says safety like this high-quality reflective tape, the same material that's used to make stop signs. You get (4) glossy, self-adhesive red reflective tapes, 12" long x 3/4" wide. We're thinking bike fenders and helmets, dog collars, garage door frames, anything that could benefit from a heightened visibility.

These are all 21” square cotton/poly blend factory-second bandanas. A few are unhemmed on one side, but generally we can’t see why many of them were seconded. Most are traditional paisley designs in assorted colors, but others are novelty versions in USA and Texas flag looks, camo, smiley faces, dog paw prints, solid colors and others. It’ll be a nice change not to know exactly what you’re getting, won’t it? Buy ’em at the bulk price and resell them. Start your side hustle now!

These here are made for repairing tents after critters tried to get inside or somebody bent over too fast with a machete in his belt. Iron these off-white canvas strips, shiny side down, over the hole and yer tent's like new, almost. Pants too, if ya got off-white canvas britches. Make good iron-on name tags, no matter how short or long your name is. Small are 2" x 2". Sold in large quantities, in case you have particularly aggressive critters, or an extra-long machete.

The Rev. Julius Arthur Nieuwland, a Fighting Irish chemistry professor, discovered what later became DuPrene made by DuPont, later wisely renamed Neoprene. The rest is wet-suit history. You, however, need it to line toolboxes, pot & pan drawers, or anything else that needs dense, black rubber padding. Our each is a sheet 38" x 7-7/8" x 3/16" thick and cheap at twice the price.

Thin-sheet-metal workers, that is. As in crafter/jeweler/model-maker types. You get a 3-pack of very nice, bendable, metal foil sheets, 5" x 7" x .005" thick, (1) each in copper, brass and aluminum.

See psychedelic patterns the safe way! Press your hand on this 6" x 6" sheet of liquid crystal and leave a print of swirling colors that, like the mood ring of yore, you can use as a sign of your mood. The pattern will blend and fade in seconds as the crystals react to temperature. Tiny liquid crystals inside the film-like material react to the heat of your hand, 25-30°C (77-86°F) by changing colors. As science, it demonstrates the way liquid crystal displays work. And you can cut each crystal sheet into pieces to incorporate into a science project. Or just leave it out for guests to play with when the party turns boring.

That’s not an oxymoron—soft hunks—but a description of actual 8” x 5-3/8” x 3/16” thick slabs of black neoprene with self-adhesive backing. Mouse pads, case liners for electronics, furniture-saving pads for lamps and vases, mattresses for gerbil habitats, you decide.

Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide  x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.
