Chemiluminescence Kit
The Cool Blue Light Experiment Kit uses copper sulfate, perborate and luminol to produce light from the energy released in a chemical reaction. The instructions recommend this kit for experimenters nine years old and up, with adult supervision. Some experiments call for the addition of household chemicals like chlorine bleach, hydrogen peroxide or sugar.

World Dimmers
Okay, polarizing filters for the literal minded. Each filter is a 20 mm dia x 2 mm think piece of glass with a couple of tiny slots in the edge. Each has 20% transmission by itself, which may not sound like much, but is about what you get through decent sunglasses. We are selling a pair so you can do experiments on transmission as you rotate one against the other to reduce the light getting through virtually to nothing. Or you can make some very cool granny sun glasses if that turns you on. The big guys get upwards of $7.00 per filter for these dudes!! Isn't surplus cool??

Illuminating Moment
A cool double pole double throw momentary rocker switch. The rocking switch lever is white plastic with a 24 V bulb in it. Wire it so the lamp is always on, flashes when pushed, is on except when pushed....whatever you want. The switch is rated for 3 amps @ 125 VAC and has solder terminals. 1" x 3/4" x 1-3/8" from the tip of the rocker to the base of the solder terminals at the back. Cory suggests applying it to your rocket launcher.

Accent Lighting
So that your wheat can see where it's growing. OK, they're really for all those teeny-light needs: dollhouses, models, robots, train sets, like that. This set was made to be a repair kit for Aura Grain of Wheat rope lights, and you can still use it for that, but you'll get an 18" length of 3/8" dia clear or colored rope with (18) white lights inside, plus (2) 1-3/4" pieces of clear shrink-wrap tube, and (2) 2-pin splice connectors. The 18" length operates at 120VAC & draws approx. 9 watts. Use it as is or slice the tube and remove the 6 volt GOW lights. Need to fancy up your train layout? Add tee connectors, and go to it!

The size of a credit card and only 5/16" thick, this flat silver-gray pocket flashlight is handy to have at hand. In addition to the momentary switch and (4) "AG-10" batteries, it has self-adhesive tape in a recessed 1-1/8" square -- just the spot for a picture of the light of your life.

Borrowed From NASA
So the concept was developed by NASA for the space program. You can use it to beef up the safety lighting on your bike. Or re-enact the Electric Horseman, or maybe just really dress up a jogging hat. It's a 30" long x 1/4" wide electroluminescent peel-and-stick strip like the government uses on airplanes. (Hey, that's what it says on the box.) It glows a light blue--in steady or flashing modes--when powered by (2) "AAA" batteries, which are not included because we can't do everything. The control box and battery case, 2" x 1-1/2" x 1" thick, is in the middle of the strip with mounting hardware for your bike. Or saddle.

Tiny Table Lamp
On tiny tables or the desktop, this lamp throws a nice puddle of light for its size. The 4-1/4" x 3" x 1-1/2" tall base supports an 8" long gooseneck with (14) bright white LEDs at the top. Silver-plastic and chrome, with a pushbutton switch on the base, it comes with (3) "AAA" batteries. We're putting ours on top of the dresser so maybe we'll finally be able to tell what color socks we're taking out of the top drawer, but it would make a nice little reading or camping lamp. Should give 15 hours of light with fresh batteries.

Lightning On Your Belt
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.

Stop. Look. Solder.
Suitable for model towns, railroads, and teaching the basics of electronics and soldering. This high-quality traffic light kit needs only your soldering iron, a 9V battery and a steady hand to yield a 4-1/2" tall, 4-way stoplight with red, yellow and green LEDs (which cycle automatically at an adjustable rate) on each face.
