Tootin' Our Laser
We don't like to brag, but it's tough not to in a case like this. This is a wonderful pen-shaped laser pointer, 5-1/4" long, flat black or silver with gold pocket clip and head. It throws a red point a loong way (we've thrown it two city blocks at night, and it would've gone farther, but buildings got in the way). And what are we so proud of? We've seen a very similar item-not identical, mind you, but essentially the same-in one of those glossy, toys-for-grown-men catalogs. Their price? $20! We're proud not to be profit-mongers, buy it here and you can take pride in your smart shopping habits. Batteries included.

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.

Sew What?
We've had our eye on this macho needle kit. It includes (7) steel needles: (1) 1-3/4" for leather, (1) 1-3/4" for carpet, (1) 2-1/4" for sails, (2) 3" needles, one for packing and one for canvas, and (2) 2-1/8" dia curved needles, one for mattresses and one for lampshades. All right. So maybe you can use the lampshade needle to sew up softballs. May we suggest you stick these on one of our magnets, so you always know where they are?

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.

Hobby Tools
We like these small pliers and cutters - they're a higher quality than most of the Chinese import tools we're offered. They are drop-forged, high-carbon steel with double-leaf springs, lap joints and rubberized foam handles. There is a trim 6" needle nose, and a 4-1/2" mini-round diagonal cutter. For precision work and hobbies, and especially nice for anyone with small hands.

Miracle Fiber
Thinner than a human hair! Smoother than a baby's bottom! More absorbent than an enthralled groupie! Its a microfiber miracle cloth. It really is amazing folks. A 6" square cleaning cloth woven of 90,000 microfibers per sq. inch, each 0.5 mm dia. Super absorbent, it can be used wet or dry to clean the most delicate lens, CD, or for that matter, your car or kitchen counter. "As seen on TV" except this one really lives up to the hype. You need several to clean super clean where it really counts. Like your specs and other coated optics.

Small Saws
Stay on the cutting edge with this sharp set of saw blades. The 1-3/4" dia circular blade cuts plastic, particle board, soft metal, etc. The 2" dia and 1-1/4" dia wood blades cut, you guessed it, wood. They each screw onto the 2" shaft with 1/8" mandrel that's included, for a maximum 8000 rpm ride on your power tool.

Mini Air Compressor
Nifty device that takes maxi air and squeezes it down into a mini condition. The device is roughly 6-1/2"" long x 6" tall x 4" wide. It has a 10 ft. cord that plugs into an auto lighter socket: i.e. it runs on 12VDC @ 10 amps. Air output is via a 12" hose with a variety of valve adapters for tires, soccer balls, rubber rafts, and just dusting off the environment. Complete with a 0-250 psi gauge. Which should be plenty of pressure to explode a weak bike tire or flimsy beach ball, so please be careful!
