BEST SELLERS

Or singing suppositories. The pair is very magnetic, whatever they are. The 1-3/4" long prolate 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.

With ours you get a choice. Our Tube-o-Pencils has (7) colored pencils, in pretty much the standard rainbow array, with erasers, in a sturdy cardboard tube that you’re free to decorate during social studies; our Quadruple-Tip Hipster Set is a black cardboard tube filled with (7) black pencils, each with (4) leads in a spiral of red, green, blue and yellow so you can make lines that are extra-pretty--or extra-trippy if that’s how you roll.

This plated N52 14,200 gauss neodymium magnet is shaped like a miniature silver ingot, measuring 1-1/2" long x 1/2" wide x 1/8" thick. Has a big hangonability quotient, which the manufacturer claims is 15 lbs of pull, meaning it's probably closer to 13 lbs. Impressive either way for such a cute little magnet. 

These are very nice 48-page, 5” x 7” cardboard-bound notebooks with themes and some unobtrusive notes/formats that will be easy to ignore if you’re not a Starship captain, artist or astronomer. You pick: the United Federation Captain’s log has a date/location entry on each lined page and fold-out info on the back cover, like a warp-speed conversion table; the Artist’s notebook has unlined ecru pages with an assortment of frame styles as borders and fold-out shading, perspective and composition info on the back cover; the Stargazer’s notebook has 1/4” rules plus a lightly printed 3-1/4” dia circle with 30-degree markings to chart the sky, plus a fold-out back cover with an astrolabe and constellation chart.

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.

Voted most likely to attract by the judges, this magnet has the relative strength of 10 men. A shiny silver 1/2" cube of neodymium magnetism, it packs approx a 15-lb pull. If our boss Pat were that strong he could lift 2,160 lbs! Besides its superpower strength, this beautiful cube also would improve the looks of your fridge or bulletin board to no end.

We're liking this little plated N45 neodymium magnet because it will stand on end and stick out very prettily on the ice box. Measures 1" tall x 1/4" square with a hefty, for its size, 3-1/2 lb pull, 13,800 gauss. (Will also lie down on its side, of course, because everybody does.)

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.

Rare earth magnets are usually killers for their size, and these thick nickel neodymium discs are no exception. The price, on the other hand, for (3) 7/16" dia x 1/4" 5-lb lift or (2) 15/32” dia x 3/16” 8-lb lift magnets each stored on a 2" dia steel disc, is a rare exception.

50 Science Things to Make and Do is just that, a passel of experiments, all illustratively explained in two facing pages of this big 104-page flip book, and all easily done with common household items. Includes wind and water power, bugs, crystals, paper planes, rubber-band guitars, balances, gloop, optics and a ton of other fun, informative stuff. Officially classified as "cool" by several of our geekiest staffers.

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+.

Call them the Founding Replicas and display them in the classroom, whether at home or in school. The U.S. Constitution is 18-1/2" x 12-1/2" and the Bill of Rights is 15-5/8" x 13-5/8", both on realistic "antiqued vellum." These are nice replicas, but much reduced in size, the Constitution in particular will require magnification for reading. Our each includes both documents.

Coated white, these ceramic magnets look kind of like little donuts, each 7/8" dia x 1/2" thick with an 11/32” ID and a pull of approx 1 lb. Extremely handy for the fridge, steel file cabinet or wherever you hang photos, notes to self, to-do lists and stuff you tear out of magazines and newspapers.

What we have here are 96-sheet, white genuine Post-It note pads, 4” wide x just shy of 3” tall with adhesive strips on the top edge. Plus, for mysterious reasons, the samples we received have letters or names (mostly girl names) strung across the top margin in pink, blue or green. Just ignore them and play a little Post-It note roulette. We'll stick our hand in the over-sized box and pull out 10. That’s why they call it surplus and that is why genuine Post-It notes are this cheap.

The 5/32” bore in the center of this small plated neodymium magnet just makes it easier to mount. Measures 3/4" dia x 1/4" thick with a pull of approx 7 lbs. Works great with #6 or #8 flat head screws.

Add a door/drawer pull to any ferrous surface with this 1" dia x 1/4" thick neodymium disc in a polished sleeve with a 3/16" dia hole in a stand-off. Comes with a 1" slip-ring attached, and hangs on for 22 lbs worth. Plenty handy for hanging stuff from other stuff, too.

Classroom and Science Fair alert: Now you can order an 8-pack of metals and metal alloys for demonstration purposes. Each pack of 1" dia x 1/32" thick discs includes aluminum, bronze, brass, copper, n/silver (w/nickel), m/steel (mild: low carbon), stainless steel, and zinc. Composition of each is stamped on one side of the discs.

Like Martha Stewart if you poured honey all over her. Also like these little 4-1/4” x 3-1/4” hardbound books of art-themed sticky notes honoring Bob (The Joy of Painting) Ross. The approx (240) notes are in large and small sizes with Bob, his easel or landscape scenes like the ones he painted.
