The Sparks Will Fly…
…when you crank up this 13-1/4" tall, hand-cranked Wimshurst generator. They were the toast of the 19th Century, and remained the hottest thing around, electrostatically speaking, until Bobby Van de Graaf came along. This one works like a top, zapping sparks to a fare-thee-well with very little cranking. It's mighty pretty too, in acrylic, white and silver, and will dress up a dull physics or electronics lab.

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.

Hombro Y Codo
Y columna vertebral. Y the bones, fractures and dislocations associated with them. All the text on these 26” x 20” slightly glossy anatomical charts featuring the shoulder, elbow and spinal column is in Spanish. If you want them for a classroom or a doctor’s office, better get them fast, before they sell out as funky wall art.
$2.00 EACH
Reaching The End Of Your Tether?
That would be approx 600 feet, if your tether is attached to this latex floater, aka “meteorological balloon for tethered flight.” These are heavier than most weather balloons, which make them perfect for parties and events. Max height is 500-600 feet. Made for filling with helium/hydrogen, and will burst at approx 8-feet dia. Our current stock is red, but don't hate us if you get a white, green or orange. Make a statement with it.
$14.95 EACH
