Newton's Cradle

This demonstrates Sir Isaac Newton's principle that 'action and reaction are equal and opposite'. If one of the steel balls is lifted and allowed to fall back at one end then one will swing out the same distance at the other end. This causes the beginning of perpetual motion which dies down only as a result of friction it's also a pretty cool thing to watch and interact with as it's a surprisingly therapeutic stress reliever. A true classic! Colour may vary between black chrome and gold.
