You Couldn't Read This...
If we'd written it with our new, gigacool blacklight marker pen with the UV LED on the other end. Unless you had one, too. It's 5" long and takes (4) LR41 button cells (included). If you ordered (2), you and your special friend could trade secret, invisible messages. Also great for UV tattoos or re-admission marks for parties and clubs, just like downtown.

A Working Wonder
If we had a category just for customers who lust after Jules Verne inventions and elegant gadgetry, this would be in it. The wonderful brass sundial, a reproduction of an antique, is approx 3" dia x 11/16" thick overall, and actually works! A latitudinal gauge lets you tilt the engraved dial to the correct angle for your location, and a bubble and three leveling feet allow the 1-1/2" dia lock-down compass to point in the precise direction. And if you never took it out into the sunshine, you'd still love it for the look and logic of it.

The Small Screen…
needs protection. Because those scratches and dings make hand-held devices hard to read and interfere with handwriting recognition. These super-thin (4 mil) plastic screen protectors were made to cover a Samsung I300™ or I330 at 1-5/8" x 2-7/16", but if you have the right specialized equipment-like a scissors, say-you could cut them to fit other sizes. Good for reducing glare and scratches on cell phones, too, Jarvis says. (He's old, but he's real techno-savvy, that Jarvis.)

World's Best Lens Cleaner
Rexton lens and optical surface cleaner cleans all optical surfaces: lenses, mirrors, prisms, windows, slides and leaves no haze. It cleans plastic or glass camera lenses, coated or uncoated. We have given some to our telescope supplier, who is an expert in such matters, and he says it is the best he has ever seen. You can even clean painted and metal surfaces. Comes in an 8 oz squeeze bottle with a flip up squirter. Absolutely the last word in cleaning for optics.

Our Flask Inventory Boileth Over
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.

Never Weaken
Good advice-and true of this dynamo torch. Actually a (3) LED flashlight, but we think the manufacturer had the Brits in mind when he named it. Has (3) LEDs and a switch that lights (1) or all (3) of them. Runs on an internal, rechargeable lithium-ion battery that you crank up-(1) minute of winding provides (30) minutes of light. (We read it on the box.) And it's a palm-sized cutie that has a very Voyage-to-the-Bottom-of-the-Sea look to it. A must for blackouts!

Light 'n' Laser Twofer
A bright little flashlight with (8) super-bright white LEDs in a circle and a less-than-5mW red laser right in the middle. One click and it's a flashlight, another click and it's a laser pointer. (Note: flashlight and pointer can't be on at the same time.) Measures 4-3/8" long x 1-1/8" dia in dark silver, red or blue aluminum with knurled grips at both ends, and comes with a black-canvas belt pouch and a wrist strap. Lasts 30 hours on a set of new alkaline batteries (3 "AAA" heavy duty batteries included).

The Mother Of All Fresnel Lenses
It came from either outer space, or a projection TV. Our largest Fresnel lens measures 49-1/8" x 37-1/8" x 1/16" thick, with a 42" focal length. Build your own lighthouse or projection TV, teach optical properties to students, or just turn your 21-inch model into one with a tavern-size picture. Held in the sun, the lens will concentrate rays enough to cook eggs or torch lumber. And, under adult supervision in the parking lot, employees of a certain un-named scientific and surplus purveyor actually melted pennies in seconds. Extremely cool and done strictly, we assure you, to determine the lens's focal length. Do not, we shouldn't have to remind you, store this puppy in direct sunlight. Or let the underage or under-mature sneak it into the sunlight.
