The purpose of this demonstration is to investigate the relationship between Pressure, Force and Area to Senior High School Students. Pressure is not a concept studied in great depth at the high school level but it is a concept that the average senior level student can understand. This demonstration teaches the students the basic relationships as well as give a glimpse into how pressure can cause an object to Accelerate. The final intent is to discover the relatively high magnitude of Atmospheric Pressure through the magnitude with which it can acceleration a ping-pong ball.
