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.

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.

They're from parts unknown and drop-offs from we know not what, but we have on our hands quantities of unused black and white PVC tubing, 1-1/2" OD x 1-3/8" ID x Approx. 7-1/2" White and/or black. We'll pick (4) pieces, our choice. Think percussion instruments or build a tubular zebra.

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.

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.
