When the Flintstones and the Rubbles visit a science exhibit, they encounter Professor Einstone and his collection of peculiar contraptions. What the absent-minded professor doesn't realize is that his "original" inventions have already been created by others—leading to hilarious complications and classic cartoon chaos.
