Why does it do that? Develop an elemental understanding of magnetism, electromagnetism, electrochemistry, radio, thermodynamics, light and optics. Simon Quellen Field's 228-page paperback, Gonzo Gizmos, Projects & Devices to Channel your Inner Geek explains processes, equipment and scientific terms -- and then, for starters, tells you things like how to make a rotary steam engine in 15 minutes from a soda can, a candle and a few scraps of rubber tubing. It's the favorite of our resident geeks -- but not for kids unless they're working with an adult. That would be a mature adult. An insured, mature adult.

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!)

It's clear that we can't describe all of these crystal-clear vinyl bags and totes. We've seen them from 5" x 2-1/2" x 5" deep to 11" x 2-1/2" x 9" deep and in half a dozen sizes in between; with white, black and no binding; with and without handles. Most have zippers, but a few don't. The vinyl in most is similar to what is used in a makeup bag. What they all have in common is that their high quality. We'll just pick out (4) assorted styles for you and save you the anguish of the decision.

Have the Time of your Life! Roll through a reel of 1960s microfilm of Time or Life magazines (that's what we've found so far).

Need a combination tweezers/magnifying lens? This one wins hands down! Elegantly simple. Easy to use. The short but wide grips on the stainless steel tweezers offer better control, but still come to a fine point. The 7/8" dia acrylic lens is only 3.5X, as opposed to the 6X claimed, but 3.5 works for most jewelers, hobbyists, scientists, and mothers of sliver-impaled children. Sweet.

Welders and other people with marketable skills know that these are sheet metal clamps, but the rest of us treasure the sundry other wonders they perform. (Wasn't that poetically put?) The handles lock, and the 3" wide jaws are just ducky at straightening out bent stuff, taking cookie sheets out of hot ovens, clamping oddly-shaped things with even pressure while the glue dries, snapping tile or glass after scoring it, and thumbscrew tightening. Made for Michigan Industrial Tools of drop-forged chromed steel, 8" long.

All in a nice wooden box with the latch on upside down-so write "top" on the top. Is that why it's here? That, and the cardboard sleeve that tells us to heed an "importan" warning.
