Optical Toy
We believe these rectangular plastic lenses were intended for the view finders in inexpensive cameras. at 15mm x 21.5mm, with a short (-80mm) focal length, and a half aluminized side, they produce a reduced scale image projected onto another image. For instance, hold the half aluminized side toward you about 4" from your eye, and look at a wall. You will see a magnified image of your eye "projected" on a slightly out of focus and reduced image of the wall!! Now move the lens about 10" from your eye, put the tip of a pen about 2" from the lens and you get a big image of the pen superimposed on a reduced image of the rest of the world. Your get the idea!! Good to muse about, explain the optics for a science project, or just use to show your friends how weird the people at American Science are. We'll send you two so your friends can show their friends!!

Screw Compressor Clamp
Used to regulate flow through a flexible tube. The screw driven jaw can be accurately adjusted in any position from closed to fully open to allow you to get just the rate of flow you want. The swing-away bottom jaw design lets you install over already connected tubing. The jaw opens to a maximum of 7/8" high and is 15/16" wide. Made of nickel plated steel, all edges are rounded to avoid cutting the tubing.

Gyroscope
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
2" flywheel in well made metal frame. The trick is the same as it has been for 100 years. Wind the string through the spindle, pull it firmly to set the flywheel spinning, and perform effortless balancing magic on pencil tips, string tightropes, and the like. We tend to forget that bicycles and aircraft navigation both rely heavily on gyroscopic principles. It's never too early to tell the kids. Besides, it's fun.

Aahhh! Bottle
At 2" sq x 3-3/4" tall overall, this clear frosted 4.5 oz glass bottle cries out for pleasantly exotic applications: like holding perfume, or sand art, or special bath oil. The narrow mouth and blue plastic cap add 3/4" height above the 3" high square shoulder of the bottle itself. Being very heavy glass, it should be safe in the bathroom. And the frosting is light enough that contents will be clearly visible. Sweet!

Tornado Tube
Simple, yet clever 1" dia. by 3" long plastic device to demonstrate the vortex effect of a tornado. Partially fill with water one of the two half-gallon size plastic soda bottles which you supply. Screw the bottles into opposite ends of the tube which we supply. Tip so the full bottle is on top and give it a circular starting whirl. Presto! You have a vortex. Call it a tornado if you're a meteorologist, a Charybdis if you're a classicist, or a whirlpool if you're into oceanography. Lots of fun and a fine opportunity to attempt to explain the effects of the earth's rotation on water draining out of a bathtub. The phenomena are related we're told, but good luck!!

Tempera Cakes
Not Tempura, tempera. Color things Dark Green or Burnt Sienna (sort of dark brick red) but don't eat these 1-7/8" sq x 3/8" thick, 2 oz cakes of dry paint. From Weber-Costello, they are called "Biggie" and sell for $2.00 in the big boys' catalogs. Don't you love surplus??

Little Glass Ampules
Terrific little glass bottles with looooong necks, in the shape called "Ampules". About half the total height is a standard cylindrical shape, at the top of this there is shoulder and above that, is an elongated tulip shaped neck. All are clear. They may have either a blue, gold or ground band on or below the "bulb" of the tulip. Bud vases for a single forgetmenot, decorative holders for colored sand or water, delicate vials for perfumes and essences, whatever the use, you just won't find them in stores. The 2 ml is 75mm tall with a 4mm neck and is 11.5mm at the bottom while the 5 ml is 88mm tall with a 6mm neck and is 16mm in diameter at the bottom. Looking for bulk savings?

Rubber Stopper
Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in blue or gray They are 3/4” across the top, 5/16” top to bottom, and fits a 1/2” (13 mm) dia opening. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

Chinex?
Rejoice, we have finally found a source of reasonably priced borosilicate lab glassware. This is the kind of glass in the trade marked Pyrex(tm) and Kimax(tm) labware. The stuff you can put right over the flame of the Bunsen burner, or directly onto the hot plate. This stuff is imported from China, and is considered student grade, which is good enough for anything but the most exotic applications. We have beakers, test tubes, graduated cylinders and flasks. Compare the prices below and you will see that they are around half the U.S. equivalent. Call us for larger quantity prices.

Mylar Warmth
They have the look of something designed for the space program. They're mylar, a paper-thin shiny metallic sheet, that comes in handy when your car breaks down in winter, or when you're separated from your climbing group on the slopes of Mt. McKinley. Barring that, they're also a perfect material for a do-it-yourself cold-climate Halloween costume-near impossible to rip by hand, but cut easily with scissors. There's no padding, so they wouldn't be too comfy on your bed, but they sure are warm. They both come folded about the size of a wallet. The Blanket is 52" x 82", the Sleeping Bag is 34" x 84".
