AIRCRAFT CABLE
Stop picturing a fat cable you can use to tie down an airplane. This is great 20–strand twisted cable from the aircraft industry, but at 1/16” dia, it’s sized more for a Chicago Cub than a Piper Cub. The cable is high–quality stainless steel, unjacketed and very strong. Use it to hang extremely heavy mirrors, make repairs, create bendable metal sculptures! Order by 15–foot hanks. Enjoy!

Scope Your Stethos!!
Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgundy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.

RED LED
An LED that really shines. The red LED is configured with a resistor and works at 9-12 volts. It's held by a 1-5/8" bracket behind a 1-1/4" x 7/16" x 5/16" deep SPST slide switch, and has (2) 4" leads. All ready to roll.

Victorian Dropper
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.

Large Rock Polishing Kit
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Budding lapidarians will lap up this rock polishing kit which is so complete it even contains some rocks. The polishing tumbler has a (3) lb. ((1) qt.) fifteen sided rubber barrel and is driven by a 115 VAC motor. Overall dimensions are 6" x 6" x 7-1/2" high. In addition to the tumbler, the kit includes an assortment of jewelry findings and a detailed manual giving you easy to follow instructions. But don't think of it only as useful for jewelry making. As a hobby, our Uncle George for many years collected and polished a wide variety of rocks which he found interesting and made beautiful in and of themselves.

A Real Grabber
Okay, it isn't the cheapest magnet in the warehouse - but we dragged John's 165 lb filing cabinet around the dock with this 4-7/8" x 1" x 3/4" ceramic magnet, we're rating it conservatively at 100 lbs of pull, and we think it's a bargain. It has a 6" bracket with mounting holes on 5-1/2" centers, plus a 1/2" ID eyehook bolted into the center of it. It's all set to troll the bottom of the lake next time your filing cabinet falls overboard.

50,000 Volts
That's what you get with this tesla coil!! Brand new, commercial item, great for classroom demonstrations and experiments. The 50,000 volt capacity generator radiates high frequency energy through space... enough to light fluorescent tubes two feet away. It uses 115 VAC (60 Hz) with an electro-magnetically operated interrupter buzzer, high voltage capacitors, inductive coil transformer, and a monopolar high frequency transformer generator to do the trick. 11" high, with a 6" sq. x 2" high protective housing for the generator. Includes accessories and instruction booklet with 19 experiments. Pretty amazing. But please, this is not a toy and should be used only under adult supervision.

Break Your Own Geodes
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
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.

Dandiest Donut in the Domain
Donut magnet you can take to town!! 74mm dia x 14mm thick with a 30mm hole. Very strong and well pedigreed - in fact, its kin are activating pacemakers. They are of a high permeability ferrite material with a lovely light blue or white epoxy coating. Okay, we have them because there is the odd bubble, slight scratches or the word MAGNET painted in the coating which ruled them out of the medical ball, but they're fine company nonetheless. Good display bases, paper clip traps, and super for classroom demos.

The Paragon
...is an inspection and dissection binocular microscope. The manufacturer says it's "perfect for industrial, agricultural, biological and educational uses." We heartily concur, which is why we're stocking this shiny new non-surplus item. "The Paragon" is 15" high, sturdy, easy to use, and has an acid and reagent resistant finish. At 10X and 30X magnification it's not for the weensiest microbes, of course, but if your work is on the scale of distinguishing weevil species, this is what you want. The 95mm dia stage plate reverses white to black for contrast, and the rack and pinion pole mount lets you view samples up to 17 cm in height. The binocular head is inclined for comfortable viewing, rotates 360°, Wide field 10X eyepieces adjust to 55 -75mm interpupillary distance. 1X and 3X objectives are turret-mounted. With the 1X objective, you get a 19mm field of view, with the 3X, a 9.5mm field. In either case the working distance is 95mm. Don't do entomology without it.
