Cage the wild light bulb in order to protect it from its natural enemy, Vandalus urbanosa. Unlike the domestic indoor bulb which can be protected with a silk or paper shade, this more-endangered bulb is found outdoors or in rugged industrial habitats. Our yellow-plastic cage is available for bulbs of 100 watts or less. (Bulb should not touch plastic.) This cage is 6–1/2” long x 5” dia at its widest point. One side has a release latch for access to the bulb. They fit over a medium-base socket to protect the lamp in it. Hardware included.

You need this. Anybody who's ever made a third trip to the hardware store on the same day needs this. The (100) -- count 'em, (100) -- chrome vanadium driver and bit attachments include slotted, Phillips, square (Robertson) head, torx, hex and 12-point bits, plus security Phillips, torx and hex, and (4) different driver adapters (one of which, a super-cute cup-hook driver, has us oddly excited). They're all in a flip-top plastic case. How come it's surplus? If you turn it upside down and shake it, some of the bits fall out of their little size-marked slots. So don't do that. Or stick a thin sheet of foam inside it and all will be well.

WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Or singing suppositories. The pair is very magnetic, whatever they are. The 1-3/4" long oblate spheroids look like highly polished black hematites. Hold them an inch apart in your palm, toss 'em into the air and listen to them make a sound like the cyber-crickets. Or an electrocuted chicken. The manufacturer suggests keeping these mega-magnets away from computers, pacemakers, TV sets and credit cards.

CJ calls it very clever, and we agree. The Soda Bottle Wasp Trap" from Gadjit® Outdoors has a sleeve that fits into any size pop bottle, plus a 3-3/8" dia x 1-1/2" tall top that screws onto bottles-onto a 1" OD neck, the standard soda bottle opening-and invites stinging pests inside for a drink. Permanently. Use regular, non-diet pop-wasps, hornets and yellow-jackets are notoriously indifferent about their weight. Includes a few wasp-themed stickers to decorate the bottle. Please note: this trap will not attach properly to the new Coca-Cola low-profile bottles.

You remember: white cardboard frames with red and blue plastic lenses. The temples fold to 5" long. 3-D's a lot more fun in these days of the Web: go to www.howstuffworks.com for binocular disparity and rivalry tests, or just Google around to find fun stuff or school optics experiments to use these with.

Nothing to it with William Gurstelle's "Backyard Ballistics," a soft-cover, 169pp compendium by an engineer on constructing rockets, cannons (carbide and spud), flingers, tennis ball mortars, balloons, fire kites, and other intriguing devices, all with common household materials. The detailed text includes parts lists, illustrated instructions, photos and quite sensible and necessary safety precautions. From Chicago Review Press.

They call it the "Krazy Cutter" and it's going to make your life a whole bunch easier. It's a little 2-3/8" long x 3/16" thick teardrop-shaped paper slicer with a teensy rust- and dullness-proof ceramic blade that magically cuts through paper and plastic. Perfect for clipping newsprint, cutting wrapping paper, and opening deviously sealed packaging, including the heavy stuff if you press a bit. Even CD cases. The krazy part? Won't cut your fingers or anything else. You could run it right over your hand, press down and everything, and nothing. Really. We tried it on some expendable employees. You know what this means? You can take it on airplanes, which further means that when you get to the coast you'll actually be able to open all the packages full of the stuff you sent ahead.
