BEST SELLERS

We’d start with triops, lovely little crustacean-ettes with compound eyes that have been around since Triassic days. You pick the Ghost Triops, see-through honeys, or the larger Gigantic Triops, the biggest of the triops which is gigantic among lesser beasts. In both cases you get eggs, baby and adult food, and a pipette. You add a bright light source, bottled natural spring water and a small tank. They hatch in a day or three, are full grown in a month or so, and have a life-cycle of up to 90 days.  Ages 8+.

OK, pay attention. This is a plug-in nightlight with red, green and blue LEDs that shift through a 2” dia prism while a small speaker plays lullabies via a recordable micro SD card. Some folks here say it put them into an ASMR (autonomous sensory meridian response) state. See for yourself. The light is gentle and random, not music driven. You can record your own lullabies, or bedtime stories, or Hall & Oates if they help you sleep. The micro SD card comes in an SD adapter and will fit your devices. Has volume and playback controls and a light sensitive "eye" for auto on/off when it gets dark or light. Measures 3-7/8" x 2-5/8" x 2". Now go to sleep.

It’s cheaper just to buy your own messenger bag. This one is light beige polyester canvas, 10" x 13-1/2" x 3-1/2" with a front flap with a magnetic clasp and side zipper that opens a 10" x 7" outside pocket. Inside is a 7-1/2" x 10" pocket with another the same size on the back. Two 5-1/2” deep open pockets on the inside, plus another zippered 7-1/2" x 12-1/2" pocket on the inside back. And of course it comes with an attached shoulder strap, 70” long and adjustable, with a sliding shoulder pad.

No self-respecting number cruncher can afford to be seen without one of these fashion classics. We'll send you (3) classic white vinyl pocket protectors in the traditional 5-1/2" x 3-1/2" size. The front flap is blank so you can add your own name, business or drawing of your favorite Star Trek character. Order quickly; It's only a question of time before these are seen on the runways in Milan.

The mother of all flashlights! At a foot long, this extra-sturdy rechargeable LED COB flashlight shines an ultra-bright 5000 lumens and has the ability to charge your phone and other devices with its USB output. Has (3) beam settings (max/low/strobe) with an adjustable slide focus and a range of 150 meters. The 6000mAh powerbank has a USB port, and comes with a charging cable. Lasts 90 minutes on high, or three hours on low. Weatherproof, and the power cord stores in the handle.

These here are made for repairing tents after critters tried to get inside or somebody bent over too fast with a machete in his belt. Iron these off-white canvas strips, shiny side down, over the hole and yer tent's like new, almost. Pants too, if ya got off-white canvas britches. Make good iron-on name tags, no matter how short or long your name is. Small are 2" x 2". Sold in large quantities, in case you have particularly aggressive critters, or an extra-long machete.

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.

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. 

From Brazil, rescued from the guts of quartz crystal antennae, these clear rock crystals are pebble sized (some maybe 3/8" long, most smaller). We're thinking classrooms and microscopes, small jewelry items, or, at these prices, a nice little bowl of crystals for the table. Each small box contains approx 2-1/4 oz of crystals. We'll send you (2) boxes, which will about fill a test tube if combined.

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 8-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.

Do you hate it when the spaces in storage boxes are bigger than the stuff you’re storing? You need this translucent plastic (polypropylene) box with (14) storage sections that can be customized by sliding the (13) dividers into your choice of (24) sets of slots. Measures approx 7-3/4" x 6-1/8" x 1-7/8" deep with a snap lid.

From ET Tech, this series 23 liquid micro-pump draws less than 300mA at 4-6VDC (5VDC nominal) with a liter-per-minute flow rate and up to a 3-foot lift. Not submersible, but suitable for hot-water apps and continuous duty. Measures 1" x 1" dia with a barbed 1/4" right-angle outlet and a 3/8" OD inlet on top. Great for fountains!

The manufacturer says these magnetic canisters are “ideal for storing desk accessories,” although anything larger than paper clips or pushpins will be tough. On the other hand, they’re just the ticket for storing glitter, confetti and other tiny craft supplies. Our each is a 3-pack of 1-7/8” sq x 1-3/8” deep white plastic boxes with little disc magnets in the bottom. Tops have windows so you can see what you put in them.

Just like (pretty much) the old steel ammo can GIs carried, and then carried home to their garage workshops, but in olive drab or black plastic, which doesn’t rust. Measures 11" x 7" x 5" with a gasketed flip-up lid, 3” latch and a 5-1/4” folding handle on top. Weighs in at a little over a pound.

Please Note: Our current stock is black and not sure when olive drab will be back.

Tired of having to hold your old, worn test leads just so to make a connection? Then it's time to upgrade your test bench. Our each is a set of (4) 36" long test leads with 16AWG wire, and booted 3/4" alligator clips on each end. You'll get (1) each in red, black, white and yellow. Also handy for hanging photos in your darkroom and laundry when you run out of clothespins.

Outdoorsy brides-to-be all across America are registering for this BPA-free modular plastic knife/fork/spoon combo. The fork and spoon snap together like a molle buckle, hiding the surprisingly sharp serrated knife inside and the recent update adds a bottle opener, making it like a Picnic Army Knife. Measure 6-1/2” long when together. Our each is a service for (4) in red, blue, orange and green. Camping utensils don’t get any utensiler.

You get a 10ml syringe of white silicone heat sink compound for use as a thermal coupling for electronics. High conductivity, low bleed and stable at high temperatures. Perfect for you electronic tinkerers out there with a sinking feeling.

The under-powered can opener we call it. This electric can opener takes (2) "AA" batteries but is as weak as the old "My dog ate my homework" excuse, so we suggest using it for parts instead of trying to open cans of soup with it. Or better yet, find a way to add another "AA" Battery. It has great parts either way. A six-way set of meshing gears and arms, a 3VDC 90mA/220mA motor that spins approx 5K (torqued out), and two-piece plastic case. Great for DIYers, hobbyists, small-motor heads or thin cans of soup. Not sold as a working kitchen can opener. 

Teacher Alert! At this price makes a great school project to show the inner gear workings of a gadget!
