It's nice to know that some things don't change. One is the Jacob's Ladder. Still made with (6) slabs of wood, each about 2" x 2" x 1/2", each a bright combination of colors, and all connected by a contrasting ribbon. Hold one end up and let the string of slabs dangle. When you flop the top block end for end, each lower slab in turn will flop end for end. Fascinating. Particularly if you are about 5 to 9 years old.

A handful of hobby motors for a very reasonable price. This Mabuchi #RE-14 motor is only 1-1/8" x 13/16" dia, plus a 5/16" x 1/16" dia shaft. It operates from 1-1/2 to 3 VDC. Under load, at 1-1/2 VDC it draws 140 mA and spins at 500 rpm, and at 3 VDC, 800 mA, spins at 800 rpm. Comes with (2) 3" leads terminating in ring connectors. If you're looking for a larger quantity, try our classroom pack of (50). It’s a bargain!
