You can start with our single aluminum tuning fork, 2-tined and 7-1/2" long. It vibrates at 256 hz, and is labeled "C". Or you can order the set that has (8) forks and a mallet with a rubber-tipped plastic head. The forks are labeled low-C to high-C and come in a fitted, latched wooden box. Unfortunately, C.J., who has perfect pitch, tells us that his pitch is more perfect than most of the tuning forks. He also says you can file the tips, tuning them to an electronic keyboard until they're perfect - and we think there's a certain cachet to telling people you tuned the forks yourself. But they are perfect, if you're using them for things like teaching principles of sound or driving the chihuahua crazy.

Eye dropper, tongue dropper, test tube dropper, petri dish dropper, anywhere dropper. Use this 3" glass dropper, with a rubber squeeze bulb to drop small amounts of liquid wherever you think they should go. You will have to measure by counting drops, though, because there are no markings on it. Also, it is called "3" because that is about how long the glass tube is. Overall, it is 4" long.

We don't like to brag, but it's tough not to in a case like this. This is a wonderful pen-shaped laser pointer, 5-1/4" long, flat black or silver with gold pocket clip and head. It throws a red point a loong way (we've thrown it two city blocks at night, and it would've gone farther, but buildings got in the way). And what are we so proud of? We've seen a very similar item-not identical, mind you, but essentially the same-in one of those glossy, toys-for-grown-men catalogs. Their price? $20! We're proud not to be profit-mongers, buy it here and you can take pride in your smart shopping habits. Batteries included.

Riffler files are most prized by sculptors, wood carvers, model makers and similar fashioners of precision objects. They come in a variety of flat, round and triangular shapes. They are usually pointed and always have a delicate curve toward the point which makes them particularly useful for working in tight and curvy spots. We have a set of (10) in an attractive red plastic case. They are 3 x 180 mm size (about 7"), and were made in China for the King Manufacturing Co. Very nice quality at a very nice price. They can cost as much as $4.00-$5.00 apiece in regular outlets.

WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
A pair of kits for ages 10 and up which will be fun to assemble and great educational aids for learning anatomy. Each is a complete, 15" tall model of the human body, including skeleton, internal organs and a clear plastic skin through which they may be viewed. Of course, what you get is all the bits and pieces. So the assembler must identify the parts, paint them (optional, paint not included) and glue them together to complete the finished man or woman. Which is what provides the fun and learning. Simple well illustrated directions and a comprehensive booklet summarizing the functions of the parts and explaining the body's systems (respiratory, digestive, endocrine, etc.) are included. A long standing favorite in our stores.

Okay, it isn't the cheapest magnet in the warehouse - but we dragged John's 165 lb filing cabinet around the dock with this 4-7/8" x 1" x 3/4" ceramic magnet, we're rating it conservatively at 100 lbs of pull, and we think it's a bargain. It has a 6" bracket with mounting holes on 5-1/2" centers, plus a 1/2" ID eyehook bolted into the center of it. It's all set to troll the bottom of the lake next time your filing cabinet falls overboard.
