  • When one of the steel balls is lifted and allowed to fall back at one end, 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, gravity and other external forces
  • Always an interesting process to watch
  • Height 11cm
  • Ball diameter approx. 14mm
  • Weight of each ball approx. 12.5g
