Hold The Cosmos In Your Hand
An out-of-this-world classroom collection, gift, or personal treasure! Meade Instruments offers this intriguing set of two dozen meteorites, tektites and impactites collected from significant falls around the world. Each 1/2" to 1" specimen is a unique shape, size, color and texture. Each was purchased from a reliable source and tested for authenticity, then placed in its own clear-plastic container in a leatherette display/storage case. Each can be removed from its container to be admired or studied under a microscope. The limited-edition collection comes with a certificate of authenticity, and a color-coded chart listing the location and interesting details about each of the (24) specimens. If you study the physical universe, teach about it, or just dream about it, this will be very special to you.

Lightning!
Well, the next best thing, anyway. 200,000 volts of electrostatic energy created by the Van de Graaf generator you assemble from the kit. Assembly is easy; you need a screwdriver, pliers and scissors - no soldering. A newspaper-like set of instructions includes lots of fun experiments. For grade 6 and up. This is not a toy and should be used under adult supervision. A great tool for teaching about electricity.

Socko X-Ray Sets
…of one human or an assortment of beasties, but we took both home and so will you. These x-rays are very useful for biology teachers, but have endless applications. Make a very easy oversized jigsaw puzzle with the human pix or, with some super glue, a great shower curtain. But the real possibilities are for artists and designers-fold 'em into lampshades, blow them up and shrink them on a copier, or scan them and have fun in Photoshop™. The human skeletal system, a complete skeleton when assembled, is in (18) sheets. The non-human set of (13) includes a marmoset, frontosa cichlid, green tree python, veiled chameleon, dwarf crocodile eggs, baby kangaroo, red-tailed hawk (oddly flamingo-like), sunfish, baby iguana, rattlesnake, box turtle, leaf frog, and a European rabbit which we think is particularly interesting. Actual x-rays are reprinted on transparencies which work with overhead projectors, and range from 3-3/8" x 6-7/8" to 8-3/8" x 10-5/8". They come with info sheets in English and French.

Me, Me, Me, Me, Mee
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.

50,000 Volts
That's what you get with this tesla coil!! Brand new, commercial item, great for classroom demonstrations and experiments. The 50,000 volt capacity generator radiates high frequency energy through space... enough to light fluorescent tubes two feet away. It uses 115 VAC (60 Hz) with an electro-magnetically operated interrupter buzzer, high voltage capacitors, inductive coil transformer, and a monopolar high frequency transformer generator to do the trick. 11" high, with a 6" sq. x 2" high protective housing for the generator. Includes accessories and instruction booklet with 19 experiments. Pretty amazing. But please, this is not a toy and should be used only under adult supervision.

Magical Flag Placemat
Another teach-'em-while-they-eat product: clever laminated placemats that display the flags of (29) European or (28) North/South/Central American countries. Rub the heat-sensitive bar under each flag and the country, capital and currency are revealed (and fade again in a minute or two). Yes, the kiddles can draw on them with crayons or dry-erase markers, and no, they don't have to be used to eat from, they could just be teaching aids. Mats measure 13-1/2" x 9-5/8".
