Physics Experiments Race beads down a straight line, an arc and a cycloid, or draw your own wire. Let beads go anywhere in a cycloid bowl and watch them arrive together. Let go of a hanging slinky and watch its bottom wait.
Physics in 3D Spin a top fast and it stands, slow and it falls. Roll a marble on a spinning record and it circles back to where it started. Watch a spring trade its bounce for a twist, and a T-handle flip itself over in space.
Physics Tricks Shake a pendulum fast enough and it balances upside down. Lift two balls of a Newton's cradle and two fly out. Throw a superball under a table and it comes back to your hand.
