Meteorological Pilot Balloon
Pilot balloons, as opposed to sounding balloons, take a very small payload and are used for measuring wind direction and speed. This one is orange, 20 gram latex and will carry 4.4 oz. Inflates to 15.75" to 17.71" and bursts between 31.5" and 35.4", none of which matters if you're just decorating the yard for a barbeque. (What does matter is that if you're decorating the yard, you should keep this delicate membrane away from sharp branches, rough concrete, canine's canines, and other hazards.)

Tired Of Iron Filings?
Same here. Try the Ferrofluid Magnetic Display, a little sealed bottle with virtually fluid nano-particles of ferrous metal suspended in liquid. You’ll get (4) powerful 1/2” dia x 3/16” neodymium disc magnets, (2) of them attached to chess-pawnish holders. Move the magnets in assorted combinations around the bottle for fascinating effects. Sort of the marriage of science with desk toys, but students can’t spill these particles all over the place.

You Fall To Pieces...
The human body is a puzzle, really. Get a head-start on anatomy class with one of these anatomically correct breakaway models in authentically colored plastic with detailed cross-sections. Pick the 2" tall, 7-piece eyeball; the 3-1/2" tall, 6-piece human heart; or the 3-3/8" tall, 6-piece rubber and plastic human head/skull/brain. All stand on 3" square bases.
