Some recent perpetual motion Tip on residence:
Invented by Mr. Reidar Finsrud, the whole machine is placed inside a glass mount, to prevent visitors who view the machine in the gallery from touching it. A steel ball (about 2.7 inch diameter, 20 pound) is rolling on an aluminum track, about 25 inches in diameter, placed horizontally. 3 pendulums, about 45 inches lengthy with tunable weights at the lower finish, controls 3 horse-shoe magnets that the steel ball has to pass by on the track.
