Make a whole bunch of fun and instructive Lego® machines/chain reaction models like marble runs and mousetraps involving ramps, buckets, funnels balances and much more. Comes with (33) Lego® elements, (6) Lego® balls, a dozen paper props, and a 78-page instruction booklet for (10) machines. You add a few common household items. Includes suggestions for more complicated devices if you have your own Lego® pieces, and if you don't, what are you waiting for? Ages 8+.

From the harmonica kings themselves at the Hohner company, comes this 4" long, 3-octave plus, plastic harmonica, in C, the people's key. We'll pick one in an attractive shade of red, green, blue, yellow or whatever color shows up next, and send it in a little vinyl case.

Geology for those with short attention spans? The original Magic Rocks®, of course! Mix the solution in a jar of water, drop in the pebbles, and watch them grow into a forest of multi-color stalagmites. Growth starts in 10 minutes, is impressive in 30 minutes, and complete (up to 4" tall) in 2 hours. Extra credit if you can make it grow stalactites by gluing the pebbles to the bottom of a jar, then pouring the solution in and turning it upside down. Who knows? Maybe it will work. Comes with a set of marine decals to decorate the jar. Definitely not for use with living fish. For ages 10 and up.

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.

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.

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.

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+.

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.

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.

Not your amateurish gag boxes, but 4-color genuine-looking boxes like you find at all your Big-Box stores, with graphics, marketing copy, testimonials and instructions. You pick the Crib Dribbler infant feeding system, just like rabbit waterers or the amusingly disturbing Earwax Candle Kit. Boxes are all 11-1/4" x 9" x 3-1/4" and are, naturally, empty. You see, the real gift goes inside. 

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.

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.

We love NASA and so do you, or someone you love does. And with the 50th anniversary of the moon landing this year (July 20), why not show your support by sticking a bunch of classic NASA “meatball” logos on your stuff? You know the one--the blue sphere and white stars with the NASA name in white, a red chevron slashing through it and a white orbiting swirl wrapping it all together. You’ll get (15) logo stickers in 1” dia ; a 3-1/2” logo sticker; a 3-1/2” window cling logo; and a good, old-fashioned 10" x 2-3/4" white bumper sticker with the logo and the following phrase: “IT’S NOT ROCKET SCIENCE! (OH, WAIT, YES IT IS!)”. Hard not to love that aerospace-engineer humor.

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.

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.

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.

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.

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.
