BEST SELLERS

Jarvis says you need this! Kitchen conversions are easy with this 3" x 4" deluxe American Science & Surplus fridge magnet that lists everything from a tablespoon to a cup with the equivalent in ounces, tablespoons, teaspoons, milliliters and fractions of a cup. If your kids already have fridges of their own, you can buy extra magnets for them - unless they were the only kids on the block who knew how many ounces were in a cup. Kitchen Fun.

25 Pieces of teeny, tiny neodymium magnets. Measuring a scant 6MM diameter x 3MM thick, and they are perfect for jewelry, hobbies, arts and crafts and a million other uses. (We would list them all but we have space limitations on our website) These shiny silver mighty mights even come in their own plastic box. A great find!

All together now, boys and girls, can you say BARGAIN? A bonanza assortment of (100) 1/8" shank rotary tool attachments: wheels, brushes, stones, sanding wheels, buffing pads, and sundry other stuff. All in a nice wooden box with the latch on upside down-so write "top" on the top. Is that why it's here? That, and the cardboard sleeve that tells us to heed an "importan" warning. Case dimensions are about 8-3/8" x 5-1/2" x 1-3/4".

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 the heat of your hand, 25-30°C (77-86°F) by changing colors. As science, it demonstrates the way liquid crystal displays work. And you can cut each crystal sheet into pieces to incorporate into a science project. Or just leave it out for guests to play with when the party turns boring.

You know those times when you don’t have a stove and you wonder how you’re going to heat up your soup or mac and cheese? Like at college, or when you’re on the road and living in hotel rooms? Times like those are when this 110VAC, 1000-watt (9A) hot plate shines. Has an easy-to-use dial with (5) temperature settings, from 140F to 716F, a neon power indicator, metal body, non-slip feet and a 3-foot cord. Measures approx 8” x 8” x 2-3/4”. This is a serious cooking tool, not a toy, and shouldn’t be used by anyone under age 12. Anyone over 12 should operate the plate under the supervision of an adult. Just one, though. Too many cooks spoil the broth. CE listed.

We’re not talking strip steaks here—we’re talking LED strips. Our self-adhesive smart WiFi strips have (180) LEDs, measure approx 6-1/2 feet long and are weather-resistant with an IP44 rating. You control both the color and the dimming via a smart WiFi app. Conveniently, a 3M self-adhesive strip is already attached, so the lights are ready to hang straight out of the box. They work with Hey Google and Amazon Alexa, and each strip also includes a power adapter.

It looks as though it should be used for administering laudanum! A 30mL, 1-1/4" sq x 3" tall clear glass bottle, it has thick molded sides and a heavy lip: very antique in appearance. It is stoppered with a red(!) rubber stopper which is the squeeze bulb for the glass dropper tube inside. A real eye catcher, but give it a good wash please. It clearly is not sterile.

Brand new 2' x 2' LED panel lights. 3000k (Warm Light) and operates on 120vac with the included driver. These panels fit into standard drop ceiling tiles and only draw 40watts of power making them ideal as replacements for larger fixtures. Saves big dollars over standard fluorescent lamps. 

Jarvis Says: Driver might be different than photo shows. 

Note: Item is not available for expedited shipping and your entire order will ship UPS ground when placing this order. 

From the mid-20th-century German military, this is a fully functional field phone. Weighs in at 8.2 lbs, and comes self-contained in a 10-1/4" x 6-3/4" x 4-1/4" dark brown Bakelite case with a handset on a 4-foot cord, a 52” 2-pin jumper, 25” TT plug cord, ringer crank and a battery holder for the battery you’ll need to add. Should work with standard stereo speaker wire, and we’d get a pair of these phones if we were you. Small quantity available. These are surplus and have wear and tear on them. We will pick the nicest of the lot. 

These brand-spanking new 12VDC motors are made to move automobile seats but are willing to change. They spin at approx 190 rpm, draw 1.5A no load, and stall at approx 25A. Threaded shaft is at a right angle and is 4-1/8" x 7/16". Shaft thread is non-standard, so treat it as a smooth shaft and mount pulley or gear with a setscrew. Measures 5-5/8" x 2-1/2" x 2-1/2" overall, not counting the shaft, and has power terminals opposite the gearbox with (2) 1/4" mounting holes opposite the shaft. If you're looking for a power supply, we've got one. Just snip the plug of this regulated switching power supply and wire it up. 

These pretty, and pretty small, polished semiprecious stones include sodalite, tiger eye, quartz crystal, aventurine, amethyst, red jasper, fluorite, and rose quartz, plus a bonus assortment. You’ll get approx 1/2 oz of each in small corked bottles, 7/8” dia x 1-1/2” tall. The semiprecious pebbles are roughly 1/8” to 3/8” long.

Go ahead—have soup, or stew, or anything gooey, without worrying about a spillage tragedy. This red plastic soup system measures 5” dia x 4-1/2” tall tapering to 3-1/2” at the bottom. Looks like a giant coffee cup, but with a gasketed screw cap that has a stubby fork and spoon cleverly hidden inside. Freezer- and microwave-safe, and BPA-free. Safe up to 200 degrees, but hand-wash only. Has a small tray and a divider inside, both of which you can ignore if you don't have a 2- or 3-part lunch. Try the beef barley, it’s excellent.

Using a word like “beautiful” to describe our newly arrived First Aid Kits seems wrong. But it’s right. They’re beautiful, and useful. Come in (3) sizes, with a sturdy, lightweight red nylon case that proclaims them “Paramedic Approved.”

You pick: the Small kit, which measures 6” x 8” x 3”, with (19) different items and (53) pieces total;

the Medium kit, 7-1/2” x 9” x 3”, including (28) items and (103) pieces total; or

the Large kit, 8-1/2” x 10-1/2” x 5”, including (37) items and (156) pieces total.

All contain the requisite First Aid booklet, bandages, cotton, antiseptic wipe, tape, shears, tweezers, gloves, saline, splinter probes and an emergency blanket (among other essentials), but the Medium and Large kits contain more specialized items, such as burn gel and fever scan strips. The Large also includes things like iodine swabs, high elastic bandages, wound dressings and an ice pack. Any size is great to have at home, and anywhere you’re on

Teensy tiny brushes for cleaning teensy tiny tubes, airbrushes, spray guns, tattoo equipment, nozzles, etc. Think miniature bottle brushes. You get a set of (5) brushes: 1/32", 1/16", 3/32", 1/8" and 3/16" dia. All have nylon bristles, are 4" long, and are on a slip ring so you won't lose them.

Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

Zivko the Robot is back in stock! Our best selling STEM kit ever! Just call her (or him--it’s unclear and we don’t like to ask) “Zivko” because “the Robot” is her last name. Using just a screwdriver and side cutters, you build Zivko from this 107-piece S.T.E.M. kit. Set the mode for “Follow Me” or “Explore,” and Zivko will, yes, track you, or evade obstacles, respectively, via an infrared sensor and micro-controller programming. Interactive LEDs and sounds abound. Measures approx 5" x 5-1/2" x 6-1/2" when assembled with all (6) legs. You add (4) “AAA”s for power, which is the least you can do for someone this cute. Ages 10+.

This QMD (Quality Medical Devices of Canada) micro-perfed surgical tape is clear, transparent, and hypoallergenic. Made for easy tearing in either direction and often used for taping down IV tubes among other uses. Our each is (12) rolls, 1" wide x 30-feet.

who's got the button? You do, which means you don't have to go the drugstore when your watch, calculator, camera, radio or nearly anything else stops. Be prepared for electronic quitters with this 30-pack of button cell batteries in the most popular sizes. Our each is (6) AG1, (6) AG3, (6) AG4, (3) AG5, (3) AG12, and (6) AG13 batteries. (Some devices may call these G1, G2, etc., or have other arcane codes for these same sizes.) Brand new!
