A good basic kit with everything you need to build a very simple crystal radio. This is not hi-tech hi-fi. Geared for ages eight and up, it is a complete kit with wonderfully straight forward instructions which walk the experimenter through hooking up tuning needle, crystal diode, and earphone, and experimenting to find useful antennas. Excellent education, recreation and discovery device all at the same time. A simple kit with hours of fun in it.

One of those sharpie East Coast outfits pulled a fast one on this poor naive Midwestern dealer. The result is we have a pile of exotic coated copper magnet wire. The coatings and colors vary widely, as does the gauge of the wire. With a couple of exceptions there isn't enough of any one kind among the hundreds in the pile to list separately. So we are offering an assortment and you get whatever we grab. Either way you will get a terrific value, particularly if you have an exotic application and get just what you need. Even if you are just making a garden variety coil or electromagnet you will still find the prices are very good. So go ahead, profit from our misfortune. We are glad to be of service. Sigh.

AKA hand boiler. An exotic bit of hand blown glass with a bulb at top and bottom connected by some zippy tubing that spirals, loops, and/or jogs. In the closed system is some colored liquid (methyl chloride) that is very light. Hold the lower bulb in you hand and as the air in the system is warmed it pushes the fluid through the loops to the upper chamber. When all the liquid is pushed out of the lower bulb, expanding air will bubble through the tubing making it appear that the liquid is boiling. WARNING! The glass is fragile and the liquid is nasty. If you drop the thing on e.g. the kitchen tile, it will eat the finish off the tile and the stain in the liquid will permanently stain the floor. So don't let kids handle this item unsupervised. About 7" tall, it is a favorite in our stores.

A collection of 11" x 14" top quality medical charts. They cover topics such as organs: "Eye" or "Skin", systems: "Digestive" or "Female Reproductive" and disease or conditions such as: "Cancer" and "Obesity". They are on heavy coated paper suitable for putting up in, say, a classroom where they would be excellent teaching aids. Most are overruns that are imprinted with the name of a drug at the bottom and were distributed as part of a promotion. A few have misspelling misprints. Because of varying quantities and a horrendous sorting problem, we cannot give you the luxury of picking your favorites from a long list. We also have (2) large (20" x 26") wall charts, One on hypertension and one on the male reproductive system.

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.

So why do you want this 7-piece watch battery replacement kit? Because it's economical and will pay for itself in short order? Because you're so self-sufficient you would have removed your own appendix if only the E-R physician hadn't been so territorial? Maybe just because you want to poke around inside a clockwork? Whatever the reason, you'll like the jeweler's Phillips screwdriver and knife, the spanner wrench, prying tool, dust brush and soft-plastic and needlepoint metal tweezers. They're in separate pockets in a plastic carrying case that can be rolled for storage or hung by its grommets. We know you'll like this kit, 'cuz we know what makes our customers tick.
