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.

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.

Can you say bulk buy? These plastic (polyethylene) dip tubes are 129mm long x 8mm OD x 6mm ID with 45-degree offset slices at each end, sold in 7,000-piece cases only. Haven't been in a lab since high school? These are 5.07" x .31" OD and .24" ID and are just screaming for an art or craft project.

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.

Whatever, but you’ll need thread. Ours is white polyester thread from American & Efird in North Carolina. It’s #46 (.0025” thick) on a 10,000-yard, 6” spool. Now that’s a lot of thread.
