A simple rotation machine
Secure a breast-drill or hand- drill like as the one shown in the diagram. Clamp a small screw eye or cup hook in the chuck of the drill. Join a 30 cm length of light string near the point end of a spike. Make a loop in the other end of the string and attach it to the screw eye in the chuck of the drill. Now rotate the drill progressively by crank. View how the centrifugal force affects the suspended spike
