About 30-40 highly polished stones, all shiny, translucent, or brightly colored, ranging from 3/4" long to 1/8" long. Great for mosaics, jewelry, or aquariums.

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. 

Or the Swanee whistle. Whatever you call it, this little slide whistle (just consider it the smallest trombone in the universe) has an outsized musical history. No elevator has ever fallen in a cartoon without its accompaniment, and no jug band is complete without one, but Louis Armstrong also played one on his Hot Five recordings, and Ravel even required one in an opera score. In assorted plastic colors with a steel slide, 6-7/8" long x 1/2" dia.

And we say that with a history of silly that’s virtually unmatched. You slip on this pair of lens-less glasses with the tiny bucket and ball on a string attached, and try, while looking like a demented chipmunk, to swing the little ball on its cord and drop it into the cup. In red and blue plastic, you will be filmed on a smart phone, it will be put on social media, and you will be famous for it for the rest of your life. Best to order a couple so you’re not alone.

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. 

Don’t you like having a thousand of something? Yeah, same here. We recommend this bag of 1,000 (we did the math, that's only 2.4 cents per marble) glass cat’s eye marbles in a rainbow of colors. Called Peewees in the marble world, they’re 12mm dia, which is 0.47”, which is like a really big pea, or a really small garbanzo bean. Play mini-marbles, or make clay cats and use the marbles for eyes, or just keep them in a big bowl for their prettiness factor.

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.

Forget that the 6-3/4" long body is festooned with Latin phrases and old maps. The stones/beads/glass inside the tube would make designing windows in cathedrals a snap. And hey, that's good work if you can get it. A nice gift for Rosetta window fans, and a must for that special bishop in your life.

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.

We love NASA and so do you, or someone you love does. And with the 50th anniversary of the moon landing this year (July 20), why not show your support by sticking a bunch of classic NASA “meatball” logos on your stuff? You know the one--the blue sphere and white stars with the NASA name in white, a red chevron slashing through it and a white orbiting swirl wrapping it all together. You’ll get (15) logo stickers in 1” dia ; a 3-1/2” logo sticker; a 3-1/2” window cling logo; and a good, old-fashioned 10" x 2-3/4" white bumper sticker with the logo and the following phrase: “IT’S NOT ROCKET SCIENCE! (OH, WAIT, YES IT IS!)”. Hard not to love that aerospace-engineer humor.

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.

Stick a coin on top of the fishy plate on this plastic coin bank and it triggers a Hiya Kitty inside to mew some cat noises, then peeks out and reaches out a paw to snatch the coin. The box, which is mysteriously made to look like an fruit crate, measures 4-3/4" x 4" x 3-1/2". You’ll need to add a couple of “AA” batteries but that’s the standard price of kitten cuteness today.

AKA hand boiler. An exotic bit of hand blown glass with a bulb at top and bottom connected by some zippy tubing that spirals, loops, and/or jogs. In the closed system is some colored liquid (methylene chloride) that is very light. Hold the lower bulb in your hand and as the liquid is warmed it pushes through the loops to the upper chamber. When all the liquid is pushed out of the lower bulb, expanding air will bubble through the tubing making it appear that the liquid is boiling. WARNING! The glass is fragile and the liquid is nasty. If you drop the thing on the kitchen tile, it will eat the finish off the tile and the stain in the liquid will permanently stain the floor, so don't let kids handle this item unsupervised. About 7" tall, it is a favorite in our stores.

Or singing suppositories. The pair is very magnetic, whatever they are. The 1-3/4" long oblate spheroids look like highly polished black hematites. Hold them an inch apart in your palm, toss 'em into the air and listen to them make a sound like the cyber-crickets. Or an electrocuted chicken. The manufacturer suggests keeping these mega-magnets away from computers, pacemakers, TV sets and credit cards.

Bigger than a baseball across the top, this is one ginormous jewel. You pick a clear or deep-translucent-blue, 24% lead crystal, cut-glass gem. It’s 3-1/8” dia at the top, tapering to point 2-1/8” deep. Could be mounted in a stunning, but really, really, really big engagement ring.

Time was, you wanted answers to questions, you had to have a magic 8-ball, but really, what would an 8-ball know? What you need is the All-Seeing Eye, because eyes see stuff. Eyes know stuff. This big eye is 3-7/8" dia with a window on the bottom that reveals the answers to your questions--like the 8-ball, except the eye is pretty much always right. This eye, BTW, is blue, like Sinatra’s. (Best get two, because eyes come in pairs.)

Good clean fun for trips to the beach or pool. This 4-3/4” rubber shark has a small human foot sticking out of its maw. Give him a good squeeze and the leg pops out up to the shin. Quickly repeated squeezes make it look like the shark is having lunch.

Very popular with elementary school teachers, these hardcover blank books let students create their own storybooks. (Middle-schoolers interviewing and making books for primary grade kids is a popular and civilizing project.) Also great for sketching, journaling or scrapbooking. Pure white blank covers with (14) sheets (28 pages) of 80-lb blank paper inside with a sewn-in binding. You pick the 6” x 8” books or the 8-1/2” x 11” versions.
