We have obtained a large number of real natural corks, mostly surplus with a few fill-ins bought commercially. They range across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc) and to use as floats. Or just use them to seal bottles that don't have closures or cry out for a decorative seal.

Oodles of tiny clear glass tubes. Open on each end, they'll work wonders when connecting rubber tubing or sticking into stopper holes (#27918 is especially perfect for that). Flint glass, so nothing too hot, OK?

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.

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.

A clever twin-lensed loupe that clips on eyeglasses for hands-free magnification. Each 1" dia, 3.3-power glass lens is at the end of a thin metal arm and swivels easily. The metal clip mechanism is about 1-1/2" long, each lens and arm about 2-1/2" long. Use a single lens, or line two up to double the loupe to a 6.6 power. Individually, each has a 3" working distance. When they're used together, it's 1-1/2".

The kids need presents for all the grandmas and great-aunts? You volunteer at the nursing home and need token gifts for your L-O-Ls? And your eyes aren't so good, either? Our each is really half a dozen pretty little magnifiers with round lenses and fancy handles. The handles are silver-bright (hard to believe they're aluminum) and all different. Each has a discreet hole in the tip for a jump ring so it could be worn on a necklace -- but it would look just as pretty on a desk. The overall length of the (6) magnifiers varies from about 3-3/4" to 5", the lenses from 1-1/4" to 1-3/4" dia. All are approx 2X magnification. Mary Ann's pick of the month.

If we had a category just for customers who lust after Jules Verne inventions and elegant gadgetry, this would be in it. The wonderful brass sundial, a reproduction of an antique, is approx 3" dia x 11/16" thick overall, and actually works! A latitudinal gauge lets you tilt the engraved dial to the correct angle for your location, and a bubble and three leveling feet allow the 1-1/2" dia lock-down compass to point in the precise direction. And if you never took it out into the sunshine, you'd still love it for the look and logic of it.

So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.
