It’s magnet wire because it has a thin enamel coating so you can make an electromagnet, motor, speaker or whatever out of it. But it’s also just nice 26AWG copper wire for craft or other uses. You’ll get (100) feet of it on a spool to do with it what you will.

OK, $1.08 per year at average usage, but what can you buy with eight cents anyway? This standard-base 120V LED light bulb illuminates like a 60W incandescent but draws just 9W. Rated for 675 lumens with a 2700K soft white color temperature. Instant-on and dimmable, with a 15K-hour lifespan. UL.

The Shape of Cool™ is trademarked. Really. And its owner is Lava® brand lamps. Accept no substitutes, we always say. Usually. Sometimes. Certainly in this case. This Lava® Lamp is 14-1/2" tall with a silvery aluminum stand and tip. It may have clear liquid with red lava; purple liquid with pink lava; or blue liquid with either yellow or purple lava. All classic Lava® colors, so we know you’ll like the one we pick out for you! All include a 25W bulb in the base. UL.

Twist the barrel of this green laser pointer and watch the diffraction lens multiply the dots and spin them in fascinating kaleidoscopic patterns. Perfect for rave parties, DIY discos, or getting kicked out of movie theaters. Guaranteed to make a cat at least schizophrenic. Measures just over 6" long and requires (2) "AAA" batteries which you will have to supply because your cat hasn't learned how to drive yet. 

Ask your grandmother, or Gloria Gaynor, how big disco was. These days disco is small enough to carry in your coat pocket. This disco light has (6) red/green/blue LEDs pulsing under a clear prismatic hemisphere that spins approx 3 rpm. You add (3) “AA” batteries for power, and then go shake your booty. Measures 3-5/8” dia (the disco light, not your booty) x 3-1/2” tall with a 1/8” mounting hole on the bottom.

Our each is a pack of (10) common cathode 5mm dia red/green/blue LEDs. Clear lens, 20mA rated for 100K hour life. 3V supply will work for all. You also get 100 Ohm and 510 Ohm resistors to step down 5 and 12VDC respectively. Luminous intensity is 4,000 mcd.

Don't hide this light under a bushel. Probably couldn't anyway, since it features (24) flashing, spinning, pulsing red, green and blue LEDs. It cycles through a variety of different patterns, looks like it came from outer space, is black or translucent white (we'll pick) and plugs into the wall via a 3-foot power cord. Mounts via (2) keyed mounting slots on the back. Measures 5" dia x 1-3/8" tall at the center. Rated for 8,000 hours of flashing fun. Click here to check out our Facebook post to see it in action.

Ten electrical leads with an alligator clip on each end. Each lead is about 20" long, not counting the 'gators. Vinyl coated 20-22 ga. wire with a vinyl cover over each clip. They come in an assortment of five colors with two leads in each color. The manufacturer calls them heavy duty but we would restrict them to the light currents and low voltages you will be using in your home experiments. Our each is a set of (10).

A failed folk-rock group from the Summer of Love? No, a trio of pretty lepidoptera oscillating through many colors via the magic of fiber optics. They have a 3" wingspread and sit on a 1-1/2" dia base that holds the (3) included and replaceable button-cell batteries inside. You'll get (3), at least (2) different, along with self-adhesive tape to stick them somewhere. We like them as party lights, but they'd also be great on a hat.

These itsy 120V neon lamps have negligible current draw and green sleeves over the lenses. Leads are 4-1/2" long with an inline limiting resistor on one. Made in the USA.

You move too fast. You got to make the mornin' last, sport, or you've got no chance at all of feelin' groovy. The Groovy Lamp is LavaLampish, but with clearer fluid that's not quite so goopy, but considerably more, well, groovy. Stands 13-1/4" tall on a 3-3/8" base and draws 25W. Has an in-line switch and 6-foot cord, and we'll pick a blue, green, purple or orange one for you. UL.

This panel-mount, grounded outlet from Eagle Electronics is rated for up 15A at 125V, and measures 1” square. You’ll need 1-1/2” clearance on the back. Has a pair of retaining clips, (2) spade terminals and a ground screw. UL/CSA.

Neatness definitely counts. Even in wiring. Especially in wiring. End those electrical mare's nests with this 6-position barrier strip, rated for up to 30A at 600V. Comes with a clear plastic cover with access to the screw terminals and measures 3-5/8" x 1-1/4" x 5/8" with a 5/16" mounting hole at each end. Terminals are in pairs.

Our laser combo pack scores you two pen-shaped 5mW laser pointers, (1) each in stopping red and going green. These colors are also perfect for Christmas, St. Patrick's Day and St. Valentine's Day. Oh, and nautical situations. The housing is flat black or silver with a gold pocket clip and head. The 532nm Class IIIa green light is 5-5/8" long x 1/2" dia, with a momentary-on switch. It's brighter than the red so it's perfect for all daytime pointer needs. The red is 5-1/4" long, and its mellow red light makes it more suitable for board room presentations but we've thrown ours two blocks at night, no problem. Green or red, whatever you do, don't cross the streams. Each pointer takes (2) "AAA" batteries, which are included.

This little light of ours has three functions and still fits in your pocket. Just 5” long in a black aluminum housing, it has a red laser, a 5-LED UV light and a bright white 10-LED standard flashlight. You add a trio of “AAA” batteries, thoughtfully linked here, and Bob’s your uncle, or at least your brother-in-law.

This 4-3/4" dia moon is so much more interesting than the real thing. This one has a 4-way dimmer, flash/strobe/fast and slow fade/steady-on modes, plus internal LEDs to make (15) colors in addition to traditional moonish white. It's also a great nightlight. Remote control comes with a battery but you'll need (3) "AAA" batteries to run the moon. Topographical, but the giant astronaut footprint suggests it's not quite to scale. Will sit up by itself or wall mount on a couple of finishing nails.

These LEDs are wired with an in-line diode on one leg so you can run them with either AC or DC. 24 volts works best (do not run them on 120V!) drawing 4mA. You'll get leads between 4" and 9" with quick-disconnect terminals. You pick yellow or red.

This tiny 3 mm LED sits in a 5/32" x 1/4" x 7/32" black-plastic box with PC board mounts. At 2-3 volts it glows green and draws 40 mA.
