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.

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!

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.

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.

You need a tarp and you know it. Our reinforced plastic (polyethylene) beauty is 72" x 64" x .009" thick (.013" around the edges) with 7/16" inner-dimension aluminum grommets at each corner and halfway on each edge. In olive green on one side and light blue on the other, this tarp will keep you dry or hide what you want to hide. OUR SURPIE POLICE SAY: MAX ORDER QUANTITY IS (4) Per Order. Any more and your order will fail in the shopping cart. Call for larger orders.

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.

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.

But you’re free to use this piece of cork rubber composite, straight from the rubber/cork trees and in a darker cork look, for anything you like, including a very small, round bulletin board, dart board. Measures 10-7/8" dia x 3/16" thick. Nice mouse pad, too, or dart board for the really accurate player who doesn’t keep score. (For some, it’s about the journey, not the numbers.)

Pure surplus: 11” x 4” x 1/4” thick oblongs (which is to say, rectangles with rounded ends) of dense, black nitrile rubber. It’s like padding, matte on one surface and glossy on the other. Great for dampening vibration, or wherever you need cushioning. Ready to use as is, and ready to cut to shape.

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.
