Find out if you are alive, and if so, whether your blood pressure is so low you will tip over when you stand up. This home blood pressure kit includes the usual D-ring cuff, a nurses' stethoscope and full instructions on their use. Not a toy, it is the real thing. Great for monitoring your health and for educational purposes. It is a two-party set, meaning it is most easily used by two people. Anyone want to play doctor?

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.

Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgandy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.

Surplus - with a silver lining! We have almost half a hundred rolls of 18-1/2" wide mylar film, the shiny side printed with a variety of balloon designs - happy birthday, happy retirement, happy other things - and a matte silver finish on the other (picture the two sides of aluminum foil). We'll send you a roll of 20 ft. Lots of craft-project potential. Start with a shiny birthday kite. Move onto hand-made hair scrunchies. Jim suggests wrapping yourself in it if your car stalls in the Arctic. Philip, always the adventurer, is considering a do-it-yourself dirigible.

Just the thing, if you're into high-style Halloween costumes and decorations and are looking for a sophisticated spider design...or if you're into unusual fishing gear. That's what these really are - (6) 2-1/2" wide x 3-7/8" long black-rubber fishing weights from Spiderman fishing sets. But one would make a very cool pendant, indeed, to wear to the next convening of the coven.

Absolutely incredible device! The Mirage®, a precision optical instrument, creates three-dimensional images of objects of your choice where there is nothing. Drop pennies, keys or similar small objects (your sister won't fit) into the 2-3/8" dia opening of this 9" dia x 3" high flying-saucer-shaped disc, and a perfect image of the object will appear floating above it. The image is so real friends will try to grasp it, but their fingers will close on thin air! Use it as a high-tech centerpiece with a flower as the object! A booklet (included) explains the magic. New coating provides protection for the mirror surfaces. Highly recommended. Made in the USA.

This skeleton is actually used in medical and other schools for teaching. The bones are plastic, but other than that it's as realistic and anatomically correct as they come. The ready-to-use skeleton is mounted with a 360° swivel at the pelvis from a heavy-duty metal rod on a stand base with castors. It has a skull with a removable section, hinged jaw and (2) removable teeth; plastic zippered dust cover; and stainless steel wire, brackets and wing nut assembly for long life. It's articulated at all joints except the spine, so you can demonstrate flexion/extension, or merely pose it in a debonair posture. Size: 5' 6" tall. Weight: 23 lbs

This sinister device seems at first glance to be an innocent ping-pong ball. Touch both of the metal strips on the weighted bottom, however, and a circuit closes, making the ball flash red and moan eerie electronic sounds. Can be used to illustrate the idea of an electric circuit to children-show how electricity can flow through a chain of people holding hands, or that a little dampness can improve conductivity, et cetera. Powered with two watch batteries (included) so there is no danger of shock.

Wow, we have 8 oz bars of Super Elasticlay, a polymer clay from those crafty guys who brought you Sculpey(tm). Create a push mold, bake it in your home oven, and voila! It retains its shape so that you can use it as a mold, but stays soft enough to pop out those Sculpey or plaster clones. Use it for flexible toys and sculptures, too. A nice statue of your significant other, maybe, that will bend to your every whim.
