This old-timey looking wooden rubber-band pistol has a ratcheting hammer that lets you load several rubber bands at once. Comes with (6) rubber bands, but you know how rubber bands are--they're everywhere.

Neon strip cardboard spectacles with diffraction gratings as the lenses. You can see the regular world, but all light sources and bright objects appear in multiple rainbow hued images. The effect is a little as though the whole world were a giant hologram. Great stocking stuffer or birthday party item for grade school ages.

We just learned that. You’d think we’d have known. Now we do. They’re sort of like round dreidels, with a hollowed-out middle around the stem, which causes them to turn themselves upside down while they’re spinning. Great lesson in center-of-mass instruction for physics teachers. Includes an explanatory booklet with activities and discussion topics. You’ll get (3) wooden tops at 7/8”, 1-1/4” and 1-1/2” dia.

Hold the bottom onion-shaped bulb of this 4" glass toy in your hand and watch the liquid (green, red, blue or purple, we'll pick) magically bubble up into the top chamber and keep on bubbling like the dickens, as your grandmother used to say. The magic is ethyl alcohol and physics. WARNING! The glass if fragile and the liquid is nasty. If you drop the thing in the kitchen it will eat the finish off the tile and permanently stain the floor, so don't let the kids handle this item unsupervised.

A good basic kit with everything you need to build a very simple crystal radio. This is not hi-tech hi-fi. Geared for ages eight and up, it is a complete kit with wonderfully straight forward instructions which walk the experimenter through hooking up wire coil, diode, variable capacitor and earphone, and experimenting to find useful antennas. Excellent education, recreation and discovery device all at the same time. A simple kit with hours of fun in it.

This whimsical pack of (30) postcards measures, unsurprisingly, post-card size 5-3/4" x 3-15/16", with non-duplicating images of gravy and bacon, Nikola Tesla, narwhals, spontaneous human combustion, boxing kangaroos, infinity and taxidermy, among many others of that ilk. Those ilks. Whatever--just buy 'em and stop asking so many questions. Blurbs on the back.

Titled "The Field and Forest Handy Book," this volume has been justifiably in print since 1906. Written by Daniel C. "Uncle Dan" Beard, the founder of the Sons of Daniel Boone and one of the founders of the BSA, it's a compendium of eternally relevant woodland lore, from building cabins, sleds, boats, and bridges to camping in swamps. The only part we skipped was on how to cook a muskrat. (We know a place that delivers.) Loaded with illustrations. In soft cover from David Godine's Nonpareil Books, 428 pages.

Interesting wire contraption that we played with as a child. A series of (4) tiers of overlapping and intertwined brass wire semicircular hoops are anchored at the open end to a pair of full circles. The whole can be shaped into a tube, double balls, a flower petal, etc, depending upon what areas are opened, which closed. A variety of colored beads on the hoops add a decorative touch. Fun, intriguing and decorative all at the same time.

The magic putty with dyspepsia is back. OK, it's fart goop, but you still wouldn't want to go to middle school without it. You'll get about 2-1/4 oz (in a color we'll pick) inside a little round plastic container that's about 2-1/2" tall x 1-1/2" dia--a little bigger than an old film canister, or roughly the size of a shot glass. Put in a thumb; pull out a rude noise.

If you remember that poster, you’re really old. Today’s generation just grabs the Decide-O-Matic, which lets it decide for them. Like the Magic 8-Ball, but with more options and more fun via a pendulum and magnet. Select a Decision Disc--fortune teller, truth or dare, movie “flix mix,” pizza picker or playlist shuffle--then set the pendulum swinging and watch it lurch from choice to choice before settling on the one that relieves you of the burden of decision-making. Includes a blank disc to add your own custom quandaries.

Great balls of air! The mighty AIRZOOKA is back--and as cool as ever! Looking like a plastic bucket with a handle and a flip-up gun sight, it blasts a puff of air up to 50 feet. Blow out candles from across the room (and avoid spitting on birthday cakes), spook the cat, disperse bugs, take target practice at styrofoam cups or buy a pair and play air-tag. Measures roughly 11” tall x 11” dia in bright green or ninja-ish black plastic (We'll pick from what's currently available.) and is, frankly, much more fun than you would imagine. Ages 6+.

From our Unlikely Combination Division comes our first-ever wind-up vehicle capable of climbing any vertical ferrous-metal surface, like your filing cabinet or (non-stainless) fridge, thanks to tiny embedded magnets. Also chugs along on the horizontal. Measures 1-7/8" x 1-1/2" x 1-3/4" tall with the winder. In assorted colors that we'll decide on, thank you very much.

Shoot one of these little plastic arrow-helicopter-rotor gismos straight up with the included rubber band launcher and watch it soar as far as 300 feet! A fun outdoor toy that grows in sophistication as you learn how to adjust the arrowcopter for wind conditions and flight patterns: distance, return, circular descent etc. Our "each" contains a package of two (2). Recommended for kids over the age of 9.

Rattlebacks are plastic semi-elliptical shapes, 3-7/8" long, that illustrate Newton's laws of motion, while mystifying kids. Set them down (the rattlebacks, not the kids) and their offset center of gravity makes them spin. Spin them in one direction and they stop and reverse themselves. You get a package of (10) in blue, along with a lesson plan and suggested activities.

Our each is tub of glitter putty, born at the confluence of silly putty and Ziggy Stardust, with (3) distinct layers of glittery gloop, which Paul, our VP for Gloop Nomenclatura, assures us are heliotrope, apple green and public swimming pool blue. Also smells like Dippity Do, but don’t put it in your hair. You’ll get 4-1/2 ounces, which is more than your mother would like you to have.

Two-tone, that is. Our each is a 1.5-oz tube of slime in two tones, and like those Chevrolets, it will come in an assortment of colors. We’ll pick the colors because, while the Bel Air was two grand and change, our two-tone is under two bucks, and you’re not going to drive it to the prom.

If you're devoted to explosions, and who isn't, you'll love the new expanded 2nd edition of William Gurstelle's Backyard Ballistics, now 25% longer, with 25% more ka-boomery. Still the go-to reference work for building rockets, cannons (carbide and potato), flingers, fire kites, electromagnetic pipe guns, tennis ball mortars, cleaner-bag balloons, ballistic pendula and petards. You simply can't have more fun with common household materials. The soft-cover, 210pp compendium includes detailed and illustrated instructions, parts lists and sensible ways not to be hoist on your own petard. Be careful out there.

You've seen everybody's favorite desk toy. The one that makes you swear you can pick up the coin that's right inside it. Too bad it's really a hologram you're looking at! Now you can own this petite version of the popular "illusion" toy. This one, 6" dia x 2" tall, with a 1-5/8" opening on the top, leaves more money in your wallet and more room on your desktop. And try to touch that little rubber frog that comes with it. It's either enchanting - or enchanted!
