# Coulomb's Law

Here, manic Princeton professor Eric Rogers hosts, continually removing and replacing his eyeglasses, ordering around lab assistants --- he forcefully breaks a glass test tube in the hands of an assistant to demonstrate the inelasticity of water --- and furiously pounds equations on a blackboard (Leacock says the scribblings must have lasted 45 minutes, in what must be one of the more necessary cuts in the history of educational film.) Rogers finally conducts an experiment with a young girl, placing her in a metal cage, which he then charges with electricity, demonstrating through the inverse square law that his assistant (Leacock’s trusting daughter Elspeth) is not harmed by the charge.
