Walking With Hands For a Mile and a Half
A magician recently claimed that he had been to New York City performing a feat that no one else had accomplished. He boasted that he had walked on his hands for a mile and a half down a typical cement sidewalk before he lost his balance and fell. What is wrong with the magician's claim?
Answer
There is no such thing as a cement sidewalk in New York City or anywhere else.Sidewalks are made of concrete. Cement is merely one of the several ingredients that make up concrete. Concrete is made of sand, gravel, water, and finally cement, which is the active agent that binds all of the materials.
