This 12VDC air pump from Parker draws approx 70-110mA and can push 25psi or suck 20”/Hg via its 3/16” barbs. Has 5” leads (red and black for power, others for controls), and measures 4” x 2” x 1-1/4”.

Beats us, frankly, but this black plastic cover, 1-3/4” x 1-1/2” x 1/4” (not unlike a tiny toilet seat cover) is hiding a really nice 1” dia x 1/8” (think: quarter size) plated neodymium magnet, with at least a 5-lb pull, inside. The mystery is that the cover won’t open unless you break it. The magnet grabs fine in the case or out of it. Tap it on its side with a hammer to crack open the case and reveal nothing but magnet.

For you reverse engineers, this 48 LED x 12 LED matrix board from Saco® has TLC5941 LED driver ICs, VHCT541 line drivers, and a PTH05060 power regulator. Has (2) 8-pin connectors for power marked with “ground” or (+). This is a sweet LED board. Some experience required. Supply voltage should be 3VDC. We think the LEDs are RGB, but there endeth our insights. Measures 17-1/2" x 4-3/8" with easily accessible data connectors.

For when your marmoset gets loose? No, silly, just a very small monkey wrench. Measuring a toolbox-friendly 8" long in drop-forged steel, this little pipe wrench opens to a max of 1-3/4” and has your standard pipe-gripping striations on the jaws.

This light fixture takeout has (8) 1/16” dia surface-mounted COB LEDs on a 1-7/8” dia circuit board/heat sink. Nominally rated for 1A at 32VDC via a 4mm ID 2-pin Molex connector. Most will have a 3/8” square clear lens over the elements. The lumens are a mystery, but it’s brighter than an MIT physics major. Color temp is warm white.

It’s a 5-draw extension shaft that extends from 7” to nearly 26”. One end has a padded black rubber handle and the other has, well, nothing. To be fair, it has a 3/8” long metal cylinder with a 7/32” ID at the business end, but for what, we don’t know. We suspect it was on its way to being some kind of pick-up tool but got distracted. As is, it’s a dandy pointer or the beginning of a clever something that you’re going to invent.

Like the Scotch, or the cookies, but this is foam. Our each is (20) 9” x 12” sheets of 1/16” thick closed-cell foam, (10) each in black and white. Get crafty.

You know those big, long pillboxes with a compartment for every day of the week? These are like that, but in a smaller, pocket-purse size, just 5-1/8” long x 1” x 7/8”. Compartments are marked with the day of the week and are 1” x 5/8” x 11/16” deep, with snap lids. In translucent white plastic.

and curved on the other? A turtle. Also half a grapefruit. Also a plano-convex glass lens, like this one (its focal length is twice the radius of its curved side). Mighty nice paperweight/magnifier too. Measures 4-1/2” across with flattened edges so it’s 3-1/4” across the other way.

This spoon-tube, originally intended to accurately measure liquid medicine and keep it off the chins of medicine-takers, will hold up to (2) tsps or 10cc/ml. In see-through fluorescent green with a little foot at the front so you can put it down on a surface without losing the contents. Measures 4-7/8” long x 1/2” ID with a 1-1/4” spoon-like tip, and marked in tsps and ml/cc gradations on the side.

After you wind the hose, extension cord, cable or rope around your hand and elbow, what do you do with the coil? We know--happens to us, too. If you had this storage and carrying strap, you’d wrap it around the coil and the coil would stay coiled. Measures 16” long and adjusts to grab bundles of varying sizes. Has a handle to carry it by or hang it up with.

Pete Seeger song. Also the way you cut tubing. As you do with this cast aluminum tubing cutter. Has a 5/8” dia carbide cutting wheel, dual 7/16” dia x 1/2” roller bearings and a folding deburring blade. For tubing between 1/8” and 1-1/8” dia.

Called the Survival Grenade, but with no grenade, this little kit has (3) lengths of nylon fishing line; (2) each hooks, swivels, weights and floats; a fire starter; some cotton tinder; a 6” square of foil; approx 12 feet of black or tan 1/8” paracord, a 2” carabiner; and a 3-edged knife/saw. The whole shebang fits in a shirt pocket.

Or turn this versatile pivoting headlamp instead. From i-Zoom®, this lamp is a serious piece of equipment, not some disposable cheapo. Has high/low/flashing modes, precise slide focus and a max of a super-bright 350 lumens. Comes with (3) “AAA” batteries in a separate rubber-covered compartment at the back of (3) adjustable elastic straps. Will pivot down (4) clicks from straight ahead to straight down. Mfr says it’s good for a 5-hour cycle on fresh batteries. Fear not the darkness with this beauty.

We couldn’t think of any clean jokes for this part, so just add your own. Meanwhile, this little, 1/4” dia, bright white COB LED is mounted on a 3/8” square PC board. Requires 70mA at 9VDC. Our in-house Fire Prevention & Ophthalmology Team suggests a heat sink as well as indirect viewing.

These digital camo-frame goggles from Voodoo Tactical® measure just over 6” across with 3/8” thick foam to protect your face and keep the sand and dirt out. The shatter-proof and scratch-resistant UV400 polycarbonate lenses are held on your noggin with an adjustable 1-1/2” wide OD elastic strap. We’re pretty sure Rommel would have ordered these if we’d shipped to North Africa.

Nothing really stops extraterrestrials, of course, but you can use this one to keep your leftover wine sealed, especially if you’re drinking in Area 51. Stick the green head in the neck of the wine bottle, push back on his little alien forehead and the bottom expands to keep it tight in the bottleneck.

We had a brother-in-law like that, but this is a Philips bright-white LED floodlight. With a medium base (think standard light bulbs), and rated for 500 lumens. Made to replace a 50W incandescent, it draws a stingy 6W, and is instant-on and dimmable. Measures 2-1/2” at the lens with a 35-degree beam angle. At (3) hours usage per day, it will last 22 years and 9 months, but don’t call us if it’s a month short of that.

This vacuum pump from Koge Electronics draws 100-250mA at 4.8V and is rated for >2.6L/minimum output and -460mbar of pressure. Measures 2-9/16" x 1-3/16" x 1-5/16" with a 3/16" OD x 3/8" inlet barb and a 3/16" OD x 1/2" tall outlet barb, plus (4) 1/8” ID mounting wings. Power terminals are exposed and you may get short leads. Koge model #KPV276.

A smaller version of the monster flood lights most of us can’t afford, this one’s rechargeable from iZoom with a 600-lumen 10W COB white LED with a 2-3/4" x 1-3/4" reflector in a water- and dust-resistant 4-3/8" x 3-1/4" x 4-1/4" with a padded 3-5/8" handle and adjustable 6-1/2" x 5-1/4" H-shaped base plus an adjustable mounting bracket. Includes a cigarette-plug charger and wall plug. Runs a little under 2 hours on a full charge.

See psychedelic patterns the safe way! Press your hand on this 6" x 6" sheet of liquid crystal and leave a print of swirling colors that, like the mood ring of yore, you can use as a sign of your mood. The pattern will blend and fade in seconds as the crystals react to temperature. Tiny liquid crystals inside the film-like material react to heat, 25-30°C (77-86°F) by changing colors. As science, it demonstrates the way liquid crystal displays work. And you can cut it into pieces to incorporate into a science project. Or just leave it out for guests to play with when the party turns boring.

Not an old codger? Get an early start. This was made for sitting on the porch, carving family heirlooms after supper. The pressboard case holds a 6-piece wood carving set with (3) small straight gouges, (1) straight chisel, (1) V-gouge and (1) skew chisel. All are approx 5" long, with wooden handles. Be even better if you used them while an old dog was asleep at your feet, but we don't sell old dogs.

Diamond files never wear out, hardly, unless you file diamonds with them. This 10-piece set of diamond files has an assortment of wedges, flats, points and triangle files, all 6” long overall and up 5/16” wide. If you can’t find the one you need here, you probably shouldn’t file the thing in the first place.

We won't say magic, what with Science being our middle name, but these cut-resistant, composite-yarn technology gloves are pretty mystifying. In cobalt blue or bright white, our each is either a pair or single glove (see description above), and since you only wear one on your non-slicing hand it's a great deal.  Lengths are from wrist to middle fingertip. They're not puncture-proof, of course, so no stabbing please, but Barb, our Director of Accounting & High-Speed Fish Gutting, was unable to slice into them. Made in the USA by Best®.

The Smithsonian knows dinosaurs, and now we’ve got dinosaur puzzles from them. Our 100-piece, 8” x 10” puzzles feature various images of the prehistoric beasts, including a dilophosaurus, stegosaurus, rebbachisaurus, mamenchisaurus and diabloceratops, or multiple dinos. We’ll pick (1) for you, because all dinosaurs are awesome. For ages 6+.

A great find: sterile plastic petri dishes, 90mm dia x 15mm deep, with a loose fitting lid. Great for growing cultures for your science fair experiments. Our each (20) dishes and lids in a sealed, sterile package.

Da Mare could use this to point out cracks in the infrastructure at Wrigley Field. You, having a forgiving nature, will resist the urge to point out cracks in da mayor's infrastructure. You will, of course, use it to point out chimney cracks to the tuck-pointer, a cracked limb to the tree-trimmer, and the crack in your profit picture during a slide presentation. You can do all that and much, much more with the bright light from this 5mW green laser pointer. It's an unbelievable tool. If you need a laser pointer that seems to go on forever and is so strong that you can actually see the beam in the dark, it will be the best low-cost investment you ever made. Or the coolest high-end toy. The 532nm Class IIIa light is 5-5/8" long x 1/2" dia, with (2) "AAA" batteries (included), a momentary-on switch, pocket clip, and case. An absolute necessity for construction, surveying, warehousing, inspection and other large sites. And for playing in the dark.

Stainless steel mortar and pestle set. Mortar measures 5-1/4” dia x 3” on a 4” dia attached saucer-like base. Holds approx 250ml. Pestle is 6-3/4” long with 1-1/4” and 2” dia heads. Nice for the lab, or for folks who want everything in their stainless steel kitchen to be stainless steel. You know who you are. And we salute you.

This take-out solenoid valve is a simple open/closed solenoid valve that is normally closed. It draws 100mA at 12VDC. Has 3/16" OD inlet and outlet at right angles to each other. Housing measures 1-3/16" long x 15/16" dia with terminals at the back end.

Wire glue-the solution when you can't find the soldering iron, don't want to bother, are out in the woods, don't quite trust a fifth-grader with a hot gun, can't reach the connection with both hands, whatever. This stuff conducts low voltage AC and DC circuits in a permanent bond and is easy to use. Our high-tech support group suggests that a toothpick is a good way to apply it. Cures overnight. Our each is a 0.3 oz/9ml jar.

Can't beat a classic. These uncoated ceramic donut magnets have a 1-lb pull, which makes them dandy for classroom or refrigerator use. They measure 1-1/4" dia x 3/8" ID x 3/16" thick and are polarized on the faces. You get a wrapped roll of 29 donuts.

Our robotic kingii dragon (Chlamydosaurus kingii, or frilled-neck lizard) is better than a puppy because you don't have clean up after it and it won't chew the furniture. This kit has (2) motors and digital control via IR sensors to activate LED eyes, motorized mouth and pop-out frill, plus "escape" and "approach me" modes, which retreat and make nice, respectively. You'll need (4) "AAA" batteries and some patience, as this kit is delightfully challenging. Finished dragon will be 13-1/2" long x 8-1/4" x 5". For ages 10+. Check out our short video on Youtube!

you’d hammer in tent pegs, all over this land. That’s what this bright yellow plastic mallet was made for, and it has those notches in the handle to help pull out recalcitrant pegs when the camping’s done. Measures 12-1/2" long with a 1-7/8" dia x 3-5/16" head, and at a mere 1/3-pound, it’s perfect for camping.

Projects include color organs, strobes, IR detection, LEDs, color spectrums, motor control, photo resistor and transistors. You can even plug your audio player into some projects. CJ, our Senior Light & Sound Boffin, called it "an enchanting rainbow of scientific theory wed to practice, with fun in the bargain," but he talks like that sometimes. For ages 8 and way up, it has over (55) parts and yes, they will play well with other Snap Circuit® components.

Check out our incredible full line of snap circuits here. 

Prick tiny bits of gunk from nasty places with these U.S. made hardened stainless steel dental tools. But please don't use them for dental work. They are slight seconds, and some may have been re-worked which only matters to teeth. Trim excess glue from models, place a barrel on the deck of the ship-in-a-bottle, clean a rasp. If you need the strength and durability in a tiny pick, you need these tools. We have an assortment of the sort you've seen laid out on your dentist's tray. We'll pick (3) different ones for you.
