Oxidation and the RA Prism
RA means right angle, which in prismese means two 45° and one 90° angle. Oxidation is how glass rusts, and it looks like a powdery white stain that won't rub off. Really doesn't interfere with the optical use of the prism, but it can be annoying. You have two choices. Ignore it and reap the price advantage, or get some of the polishing compound you use on auto windshields, buff off the surface, and reap the price advantage. These seconds have chips and/or surface scratches. Use them as spectroscopic prisms, put two hypotenuse to hypotenuse as beam splitters. All have 1-1/2" legs and 2" hypotenuses. The thickness varies as noted (sizes are approximate), and the silvered ones (sil) have a reflective coating on the hypotenal face while the plain ones (pl) don't. Remember that the silvered ones, which may make better periscopes, don't work for spectral experiments or as beam splitters.

Beach Bimbo
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Hot-pink scuba gear, turquoise water-ski equipment, purple beach accessories - everything for a day of water sports, but sized for that over-endowed fashion doll whose name we can't use. 14-piece plastic set comes with instructions that even cover the babe's speedboat, which isn't included.

Scope Your Stethos!!
Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgandy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.

Wow! Double Wow!
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
This is Philip’s new favorite toy, since he blasted a rocket so high over our parking lot that he lost sight of it (the rocket, not the parking lot). The Air Burst™ Rocket system has a 26” tall, air–powered tri–pod launcher made of plastic and rigid foam. A 65” long air hose connects it to any stand–up bike pump. After a few pumps, the air pressure bursts a replaceable booster disc in the launcher and sends a 10” x 3/4” dia rocket 250 to 1000 feet into the air. Wow! The system includes the launcher, (2) rockets, and (60) boosters (two different weights). Sending rockets out of sight, even if they usually come straight back down, is an ingenuous ploy for selling extra rockets. Our each is a pack of (2). And having extra rockets is an ingenuous ploy for selling extra booster discs. Our each is another bag of (60). No bicycle pump? The 18” black Tech Team pump blew majestically through a “double bozon” booster for us! It creates up to 120 lbs of pressure while most pumps will only generate 80 psi. It fits a Schrader (American) valve. Warning: The Air Burst™ Rocket is for ages 10 and up, with adult supervision. Don’t let us catch you out there without a kid!

Incredibubbles!
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
We love these! You're going to love these! Your kids are going to love these! Hundreds of clear marble-sized bubbles can cover the floor, cling to the sides of furniture, land on your arm. They float enchantingly, rising on air currents you can't even feel. After a few seconds, the bubbles are hard enough to catch or stack. Some will still be perched in out-of-the-way spots a day later. Touchabubbles goop, thicker than the bubble-blowing liquid you're familiar with, comes in a 4" plastic test tube with a wand built into the cap, and a clip on the side so you can carry it in a shirt pocket. The goop is nontoxic, but it tastes really bad, and you probably won't want these landing on expensive tabletops, so kids under 8 should have adult help with them. They should be sharing the fun anyway!

Alien
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
This sinister device seems at first glance to be an innocent ping-pong ball. Touch both of the metal strips on the weighted bottom, however, and a circuit closes, making the ball flash red and moan eerie electronic sounds. Can be used to illustrate the idea of an electric circuit to children-show how electricity can flow through a chain of people holding hands, or that a little dampness can improve conductivity, et cetera. Powered with two watch batteries (included) so there is no danger of shock.

Duck!
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.

Super Balloons
WARNING: CHOKING HAZARD-Children under 8 yrs. can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.
Bright and bouncy, these thick colorful balloons inflate to a super 30" dia! Great for homemade weather balloons, giant whoopee cushions, fun in the pool, or just kicking around the yard. Need strong lungs to inflate, so these aren't for smokers; swallowable, so they're not for kiddies under 8 either. Assorted colors.
