Gyroscope
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
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.

Closeup
Designed for watchmakers, this aluminum loupe with a 1" dia, 10x glass lens snugs to your eye, but leaves your hands free, thanks to the flexible 15" headband that encircles your head. It has a 1-1/2" working distance, and would come in handy, too, if you poke around in needlepoint or manipulate anything miniature.

Puff the Magic AirZooka
Mega-cool toy air cannon. Birthdays will never be the same! The instructions on the AirZooka" say it blasts a gust (ball?) of air up to 20 feet but we blew out a candle at 30 feet, and it only took us three tries. (And you can hear the near-misses as they blow past--which is the mega-cool part.) Plastic, 11" dia x 10 1/2" deep, like a bucket with a pistol grip and a fold-down sight. The (3) segments unscrew and collapse for storage between birthdays. We'll pick fluorescent blue, green, magenta or orange, and you'll need two if you want to have air wars.

Bright Box Of Rocks
Straight from the hand of Nature, and Scott Resources, comes this boxed collection of (15) 1" to 1-1/2" fluorescent mineral specimens, such as hackmanite, turritella agate, aragonite, travertine, willemite, resinous coal, selenite gypsum, fluorite, calcite, scapolite var. Wernerite and fossil algae. All are very interesting, and a few colors really pop under ordinary blacklight -- but we have to admit that today's fluorescent paints and laser shows have spoiled us for the more subtle glow of a rock. Buy these for their educational value, not their dramatic display.
