Neon strip cardboard spectacles with diffraction gratings as the lenses. You can see the regular world, but all light sources and bright objects appear in multiple rainbow hued images. The effect is a little as though the whole world were a giant hologram. Great stocking stuffer or birthday party item for grade school ages.

What’s left of a Kansas City cow after all the steaks are gone? Lots of leather! (Think buckskin, not biker jacket.) You choose from: 1) The one-piece Lace Leather Belly. Really more of a long half-belly, this solid piece of leather is between 2-1/2 and 3-1/2 sq feet. Ours was black, approx 10-1/2” wide x 53” long x 1/8” thick. 2) A pack of Leather Strips. Ours was a very assorted 2 lbs of strips and larger pieces of leather, 1/16” to 1/8” thick, in rust and brown. 3) The Farmer Bundle Repair Bag, 2 lbs of scraps in various colors. Ours contained a solid 12” x 8” black piece and a very large bundle of brown leather thongs 47” long x approx 1/8” square. Lots of variety, and lots of heavy leather for the price.

Despite parental advice, here's a good reason to sit in in a dark room and think small. This Plasma Storm isn't as large as a standard plasma ball, so not only is it much more affordable -- the effect is concentrated and startling. The black plastic base has a switch. Turn it on at which point the 3" dia plastic globe (think baseball size) is filled with blue stems that flare to pink, looking like dozens of electric flowers searching for a way out. Very cool. Comes with a 6-ft power cord with transformer.

We wouldn't try to capture 'gators with it, but this 4-ft x 6-ft black nylon, elastic (not-un-bungie-like) cargo net should trap anything else in the back of the pickup, van or kids' bedrooms. Stretches to about 6' x 9', with openings that are 7" square, stretching to maybe a foot, and 16 carabiner-style plastic hooks. Or just hang a couple on a wall for a nice Spiderman effect.

Our fashion buyers are just back from the shows in Milan with these brand new, nice quality, 80% poly/20% cotton lab coats. These are Euro-sizes, which generally (and generously) match chest circumference. The 42 has 34-1/2" sleeves, and the 48 has 36". All are about 39" long, which means fingertip length or mid-thigh, depending on how long you are. Think men's small, large and XL. They're all five-button, with one breast pocket and two large side pockets and have no name or embroidery added. Notched lapels, no vent-just what all the best-dressed technicians are wearing this season.

So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.

Brought to you by our portable plasma device. The 2-3/4" dia flat disc has a full-on mode or will pulsate to the beat of the music with red, blue and green lightning streaks, but the sensitive sound sensor also produces great results when you talk near it. The disc sits on a 2-1/4" x 1-3/4" x 5/8" thick case with a belt clip, or could be hung on a neck lanyard. (The lightning will also follow your fingertip if you touch it!) Call it a disco-must (the darker the room the better) or just wear it any time you feel like pulsating. What powers this bad boy? The (2) "AAA" batteries that you provide.
