Our PC-9 rubber-band powered styro airplane boasts a big, long rubber power plant, plastic prop, and landing gear. Measures 15" nose to tail with an 18" wingspan. Takes some light assembly but, the directions say, "when you play this plane very proficiently, you will find that it can be made more wonderful flying ways." Indeed. Rated for 200 feet of flight (80% longer than the Wright brother's first flight!), but we'd avoid really windy days for the best proficiently flying.

A touch darker blue-gray than your usual Alice Blue Gown, these are made of a better-than-paper, not-quite fabric (that we wouldn't wash if we were you) with white cotton knit cuffs, and can be worn front- or backwards. They're made for your local sawbones to wear in the O.R. In XL with front ties, and a hook-and-loop neck closure. We're thinking workshop cover-up, disposable travel bathrobe, painting smock, or just a handy thing to keep in the trunk of the car for those unexpected roadside kidney transplants.

For fun or science. And it's not actually smoke, but a fog created the same way they do for movies and heavy metal concerts. The Zero Blaster is a ray-gun-shaped, black-light-sensitive pistol that pumps out 2" to 4" dia smoke rings (rotating toroidal vortices, to be exact) that will, one after another, waft up to 12 feet away for hours of good, clean fun. Measures 9" long x 6-1/2" high. The Wizard Stick is a fog-producing wand, 10" long on a 4-5/8" x 2-1/4" base, and comes with an instruction manual for science experiments and special effects, including making wind tunnels and a vapor-ring blaster. Also good as a household draft-finder. Each takes (6) "AA" batteries, not included, and comes with a 3-ounce bottle of non-toxic fog juice, good for 25,000 smoke rings or a whole lot of fog. Better order an extra bottle of Super Zero Fluid, the replacement juice, just in case.

Sextants came along after astrolabes but before GPS. (Just like you.) They're used for finding latitude and the distance between objects, and are still the non-electric, non-satellite-dependent back-up for navigators. Ours is a beauty in solid brass with glass optical components, at a tiny price. Measures approx 4-5/8" x 4-1/4" x 3-1/4" OA and comes in a very nice wooden case. Includes instructions for use, which you're going to need unless you went to Annapolis where they still teach it because computers can still go all kaflooey. (Note that well before computers started going kaflooey, compasses and sextants lost an adventurer here and there, too, so don't call us if you and the sextant set out for Madagascar and end up in Iceland.)

This two-piece bike safety light has a bright headlight, 4-1/2" x 2-3/8" x 1-5/8", and a 3-LED red taillight, 2-5/8" x 1-7/8" x 1-1/8", that will run steady-on, slow flash, or fast flash. Both will slide out of their handlebar mounts: the headlight becomes a mini-flashlight, and the tail light has a belt-clip for jogging visibility. You add (4) "AA" batteries for the front light and (2) for the taillight.

Try a convex mirror. This lightweight, chromed-plastic version measures 2-3/4" x 1-3/4" and is on a self-adhesive swivel mount. Might help you live with your car's blind spots; might be useful for other purposes, like keeping an eye on the whole room behind you, or that hidden spot in the hallway ahead of you.
