Newtons Cradle
For every action there is an opposite and equal reaction. This theorem was proposed by Sir Issac Newton years ago and it's still the basis of modern physics. This contraption features a stainless steel finish and nylon cords that hold the miniature spheres in place. It's a great way to impress or perhaps annoy your co-workers. Be warned however, that if you are approaching the edge of a black hole, this item may not work as Newtonian Physics break down, but on planet earth and your desktop it's guaranteed to be a hit.
