Watch The Monkey's Uncle
- 1 hr 27 min
A wealthy philanthropist promises Midvale College a large donation if anyone on campus can invent a flying machine that is powered by man rather than fuel. Merlin Jones succeeds not only in developing a light-weight aircraft, but also an elixir that will make the man piloting the plane strong enough to provide constant power by pedaling. But when the day arrives to test the plane and the elixir, some disturbing information comes out about the donor who promised the prize money.
