Blacklights!!!
Your choice of (4) different kinds of these wonderful lights that are all but invisible, but make whites “glow in the dark”!! Great for Halloween parties, dances, and stimulation of any phosphorescent materials. To avoid eye damage, please do not look directly at the filament of the light. The bulb types are a regular household shaped 60 watt bulb or a 75 watt spotlight shaped bulb. We also have (2) models which come complete with a lighting fixture, reflector, and 18” blacklight fluorescent tube: The fluorescent indoor model has a 18 watt bulb and 6 ft cord for a standard 120 vac wall outlet with a switch; the car model comes with a 15 watt fluorescent tube and 15 ft cord for a cigarette lighter outlet. Great goolish fun! (Please note: The "bulb" types do not glow as well as the flourescent types)

Dichroic Filters
Dichroic filters separate light by selective transmission and reflection depended on the wavelength. These examples are 69 x 97 mm (about 2-11/16" x 3-7/8") x about 1.8 mm thick. The "yellow" filter TRANSMITS yellow, and reflects all other colors. (Reflections therefore have a violet hue.) Good for lab demonstrations or projects, possibly for photography too.

Lab Stand
Affordable, adaptable lab equipment for serious scientists with laughable budgets. The basic stand is heavy black metal 8" long x 5" wide x 1" high with a 19-1/2" x 3/8" dia support rod screwed into it. Position a beaker or bunsen burner on the stand and build the configuration you need above it. Both of the Burette clamps and the ring attach to the rod with thumbscrew clamps. The Burette clamps have wing nuts so they can be adjusted to any angle. The single clamp extends 4" from the rod, with rounded, uncoated, adjustable metal jaws with spring tension and a wing nut. The double clamp like it has rubber-coated jaws. The 3" metal support ring holds the 6" x 6" heavy-gauge steel-mesh burner screen with crimped edges. Nice, solid equipment at a rare price.

Half Past Banana
Resist the urge to just plug the electrodes into a nectarine and tell people what a sweet little clock you have. Read the few enclosed pages of background material and the explanation of the electrochemical reaction in an organic battery, and stagger your fans with your brilliance. Schylling's Fruit-Powered Clock kit also includes a 2-1/4" x 1-1/4" LCD clock/calendar, leads, a jumper wire, a stand, and complete instructions. You supply the fresh fruit. (It also works with a potato. Ain't science wonderful?) A great teaching device for 8-year-olds and up. No soldering required.

Heat Filter
A little pricey for a 2" x 2" x 1/8" thick piece of clear glass, until you figure that this is pretty darned talented glass, and that it filters heat and reflects infrared and ultraviolet rays. Then it's a bargain!

Slide Show
Microscope glassware for examination of blood, pond water, mold, and other minutiae. All of the microscope slides are optically clear glass 26mm x 76mm (about 1" x 3"), between 1mm and 1.2mm thick. The well slides, of course, have a concave well to hold a drop of liquid. Our each is a package of (12) well slides, or a box of (72) standard slides with ground or beveled edges. Cover glasses are the smaller and very thin pieces of glass used as the top of the glass slide sandwich. They are often used temporarily by simply dropping them onto a drop of liquid to flatten and spread it and to minimize evaporation. More confident microscopists will cement them in place to permanently preserve a specimen. Our each is a package of (100) cover glasses 18 mm square, #1 thickness (0.13mm to 0.17mm). If you need one, you need both.

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.
