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.

A Pyramid of Prisms
Polished glass equilateral prisms. Equilateral because each edge of the end is the same length, 32mm. Thus, as all you geometry students know, each of the angles is also the same, 60 degrees. These are school grade and are fine for decorative and demonstration. They do a nice job of diffracting light to produce a nice rainbow-like spectrum, but are definitely not up to instrumentation standards. The missing dimension, length, is shown below.

Starfinder
Whether you're a beginner or an experienced stargazer, with or without a telescope, you'll get more out of the night sky with a Miller Planisphere. This 10" rotating double disc is a map of the planets, stars and constellations, useful across a large range of the northern latitudes, although most accurate in the range of 35° to 45° north. It can be aligned to the time and date in your location to display a detailed map, and includes tips on finding the planets, suggestions for telescope projects, and more. It's an invaluable learning tool that makes stargazing a lot more fun.

Capital of Belarus? Minsk!
If they saw this color map eight times a day, they'd know where every place is-and its capital. Snap this tough, 8.5" x 11" laminated sheet into a school notebook and eventually they'll have to read it. It's a very nice world map with capital cities on one side, a U.S. map with state capitals on the other. It includes other major cities plus partial Canadian and Mexican bonus areas. Current, barring a coup since we got our latest shipment.

It's A Smaller World After All
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.
Our plastic globe inflates like a beach ball, but is a soccer ball-ish 8-1/2" dia. That still leaves enough room for countries, capitals and major cities, plus assorted ocean currents and time zones. Perfect if you want to kick around a few geography questions with the kids. You blow it up from the North Pole. World-class price.
