This small stainless steel fine-mesh filter is 2" dia x 1-1/2" tall. It has fine mesh sides, a solid plastic bottom and slight lip around the top. Nice for small filtering jobs, but would also make a passable basket for a gerbil hoops game.

Put 'em on a sheet of paper (or glass, or plastic, or any number of things), put a magnet underneath, and watch them do what iron filings do when they meet a magnet. Weird fun coupled with basic physics. Our each is 3/8 oz, which is approx 146 gazillion iron filings, and pure hell to clean up unless you have one of our handy-dandy aforementioned magnets!

Don’t put this shaker jar in the wrong place--it’s just a clever way to store and use iron filings for a physics class. You’ll get a clear glass spice jar-looking jar with a screw cap that lets you dial small/medium/large openings. Inside is 12 oz of iron fillings, 40 to 80 microns, the equivalent of grains of sand.

Black neoprene gaskets in a variety of sizes and shapes: loops, hoops and flat. Stretchy, a little dusty, but in good condition. The small round assortment gets you (2) gaskets, approx. 1/2"  dia cross-section, in loops with overall diameters between 1 and 3 feet. The large round assortment gets you approx. 3/4" dia. The Flat assortment is pieces that make loops of 2 to 5 feet dia. The rubber is about 2" x 1-1/2", but the shape varies: could be square, grooved, V-shaped, or something else. Use as is for really big valves, or better yet, chop it down to size. A great way to get cheap rubber materials for your non-critical applications We'll pick the exact dimensions and, in the case of the Flat assortment, the shape you get.

You've found perfect tires for your model of an LEV-SFC (that would be Lunar Exploration Vehicle, Stable Foot Class). StableFeet" are groovy blue plastic tubes, closed (except for a small hole) at one end. They're 3-1/4" long, and are made to fit over a standard 1-1/8" steel tube, like, say, the T-legs of an ironing board. If you don't use the striated rubber extenders to stabilize an ironing board or dress up tricycle handlebars, though, you'll have more left for your MEV-SFC. Our each is a package of (4).

Flexible, strong and wiry. No, not one of those guys who climb rock walls for fun. We're talking about our roll of 24-gauge (.023") solid wire that we believe is stainless-steel. Perfect for the workshop, and a nice weight for hobbies from bead-stringing to wreath-making. We'll clip off 20 ft to share with you.

Perfectly suitable for all your non-professional ping-pong-ball applications. These guys are white-ish, with a visible seam, and are 37mm in dia, as opposed to the standard 40mm or the former standard 38mm professional ping-pong balls. Priced so you can buy enough to do any number of clever things with them.

Closest we can come is that this was part of a meter kit, but we don't know what part. It's a 1/2" long x 3/8" wide nearly triangular black-plastic tube with sheave through the center, attached to a 7/16" x 13/16" thin wire frame with a mounting hole. Looks like the rear sight on Spock's phaser, but may have been a bobbin or wire guide of some sort.
