And more. This accessory kit for smart phones (works with iPhone, Samsung, HTC, iPad, tablets and many others) has a 2” long clip-on bracket with screw-in macro, wide-angle and fish-eye lenses. Paul loves his kit and he’s our optics expert. Use the macro for insects, coins and diamonds. Fish-eye and wide-angle for great visual effects. Includes a little pouch to carry it all in, and tiny lens caps.Note: Two lenses come threaded together to conserve space.
These 5-5/8" wide cardboard solar eclipse viewing glasses filter out 99.999 percent of visible light, and 100 percent of harmful UV and IR light, which means they’re safe for direct solar viewing (and your sunglasses aren’t). A sharp, orange image of the sun will always be there because the lenses are scratch-resistant. You get (2) pairs because who wants to watch an eclipse alone? For you techie types who care, they’re rated for transmission under EN1836:2005 and AS/NZS 1338:1992. ISO 12312-2:2015.
More fun than a canned ham, this flip-top storage tin has a train set inside, with a plastic steam engine, tender, boxcar and caboose, as well as a 12-piece track that forms a 10" x 22" oval. You add a "AA" battery and you're the engineer.
No, it doesn't; it runs out. See for yourself with this hourglass full of iron filings. The steel base has a magnet, so time flies when the glass is on it, and the filings make pretty stalagmites. Stick a magnet on the neck, however, and you can stop time altogether. Glass is 5-1/2" tall on the base and filings run out in about 40 seconds (three trips make a two-minute egg) with the magnet, somewhat longer without it.
Here's a replacement bag. We sell 'em by the pound: the half-pound bag will get you an assortment of approx 35 colorful glass marbles of various styles, ranging from 9/16" to 1-5/16" dia, although most of them will be the smaller sizes.
There's optical science and high school physics, and then there's making pretty colors with this little 4-1/2" x about 1" acrylic prism. It makes the same rainbows that the beveled edges on the glass in the French doors to your grandmother's living room used to make on the floor in the afternoon while she was making supper. If you had a grandmother with French doors with beveled glass, who made you supper. If not, you'd better buy this prism or you won't have anything to remember after she's gone.
2" flywheel in well made metal frame. The trick is the same as it has been for 100 years. Wind the string through the spindle, pull it firmly to set the flywheel spinning, and perform effortless balancing magic on pencil tips, string tightropes, and the like. We tend to forget that bicycles and aircraft navigation both rely heavily on gyroscopic principles. It's never too early to tell the kids. Besides, it's fun.
Spin the ribbed 7" handle of this hand-powered prop between your palms, and watch it take off. (If it lands instead of flying off into the wild blue yonder, reverse the spin!) Neon handle, bright, metallic-flaked 8" propeller, and a lift so high we imprinted it with our logo - the airborne Jarvis. It's all plastic, and won't decapitate anyone, but it's still for 10-year-olds and up.
Multiple game sets don't come any cheaper. You make a checkerboard and we'll supply the checkers. You get (3) sets of standard, 24-piece, 1-1/8" dia, black and red plastic checkers with the traditional grooves to make kinging easier. Nice rainy-day project for a passel of bored kids, checkerboard creation.
