the Duoscope magnifies 40 to 400 times

The right angle design also enables mirror-like effects - just twist the prism slowly round to catch the various angles - sometimes you'l see two images

Large Newton's Cradle Magnifiers and Microscopes classical style with both theThe Newton's Cradle is a modern classic, invented in 1967, but demonstrating observations made by Newton, involving the action of a pendulum, and showing the Laws of Conservation of Momentum and Energy. When a ball at one end is pulled up and let go, it swings down and hits the next ball. The energy and momentum from that action is transferred through the balls at rest, which remain immobile, and then the ball at the other end is propelled outward.
