G.I. Can Openers

Newly manufactured P-38 Can Opener from the same folks who supply them to Uncle. It folds! into 1-1/2" x 5/8" flat piece which is easily carried and lost. Reportedly works much better than the Asian knockoffs for those who really want to gain entry to the Spam!

Dancing Colors

Hang this holographic prism in the window for delicate, changing color effects. As the sun shines through, it throws splashes of red, yellow, green, blue, violet and more around the room. The glass disc is 4-1/8" dia x 1/4" thick with a chrome-look frame. Comes with a suction cup hanger to mount it on a window. (Find a way to make it rotate for an especially cool effect!)

A Working Wonder

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.

Filthy Lucre

Warning!  WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.

For archeologically minded numismatists, now comes the "Dirty Old Coins" kit, complete with (5) genuine, hand-struck ancient coins from 1,500 to over 2,000 years old, all with their own authentic dirt and ancient schmutz still attached. All "Made in the Roman Empire. Assembled in the U.S.A." You get a 12pp instruction booklet, a PC or Mac-compatible CD-ROM coin image database for identification, a stiff brush, double-lens magnifier, and cleaning and de-corrosion fluids. Most coins will be worth a few dollars, the supplier says, but some rare finds could be worth "hundreds or even thousands." Plenty of fun either way.
