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.

Wethinks this is a glass, mirrored halogen lamp reflector, but it could also serve as the shade for a pendant lamp. It’s a honey in any case. Measures 4-1/2” across x 3-1/4” deep in a parabolic shape with hundreds of small mirrored sections inside and out. Has a 1” ID hole where a lamp neck could go, with a 1-1/2” OD x 3/8” neck. Bottom edge also has a 3/8” lip around it. Could also be the most formal funnel ever made, or a candle holder if you put a blob of putty under it. Or a sparkly princess skirt if you stuck the top half of a Barbara doll into it.

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.

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.
