WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
It's a one-foot-wide world on this 12" dia inflatable globe/beach ball and it couldn't be more accurate, since the world is depicted in genuine, if small, satellite-photo images (It IS a big blue marble!). Perfect for an eerie, after-dark game on the beach, too, because the ball lights up with an internal LED powered by the (3) button-cell batteries in it. Almost unearthly!

Why does it do that? Develop an elemental understanding of magnetism, electromagnetism, electrochemistry, radio, thermodynamics, light and optics. Simon Quellen Field's 228-page paperback, Gonzo Gizmos, Projects & Devices to Channel your Inner Geek explains processes, equipment and scientific terms -- and then, for starters, tells you things like how to make a rotary steam engine in 15 minutes from a soda can, a candle and a few scraps of rubber tubing. It's the favorite of our resident geeks -- but not for kids unless they're working with an adult. That would be a mature adult. An insured, mature adult.

Way inside? Try our human X-rays. These are from Roylco® and are very useful for biology teachers, but with lots of other applications. Make a very easy oversized jigsaw puzzle or, with some super glue, a great shower curtain. But the real possibilities are for artists and designers: fold ’em into lampshades, blow them up or shrink them on a copier, or scan them and have fun in Photoshop™. You get the human skeletal system, a complete skeleton when assembled, in (18) sheets of various sizes, reprinted on transparencies which work with overhead projectors. Info sheets in English and French.
