Perpetual motion, Leonardo da Vinci
by RichMac, published
A model made from one of da Vinci's drawings. This is an elegant and simple version of the 'overbalanced wheel', which supposedly has more weight on one side and will spin forever.
A fun model to make, with an interesting history.
Designed for 8 mm balls, but 5-10mm will work.
Perpetual motion doesn't seem to work, what am I doing wrong?
