Mini Moto
Manny Moto's kid brother? Not at this price. This little hobby motor runs on 1-1/2 to 3VDC and draws approx 400mA while spinning between 700 and 1400 rpm. Hobby size, too: 1-1/8" x 3/4" with a 5/16" long shaft. Dandy for solar-power experiments, our motor maven says.

Prehistoric Poster
So the poster is really brand new. The animals on it are (1) to (190) million years old, and if that doesn't qualify as pre-history, may we stumble over a glyptodon in the dark. Invicta Plastics Ltd. of Leicester, England, printed this 23" x 16-1/2" poster with a colorful diorama to promote their authentic scale models of prehistoric animals. A time line across the bottom lists dates and data for a dozen of them, from the plesiosaur to the woolly mammoth, and compares their sizes to that of a pair of five-year-old children. Post it on the fridge to spark supper discussions, or in the classroom as a source of extra-credit questions for science quizzes.
