Beakman's World: Why do we Breathe?
13:32 - 19:03

Beakman talks about how important oxygen is and why we need it to live. Beakman acts like Joseph Priestly to explain that oxygen is needed for us to create energy. He uses an engine and a candle as demos to explain the need for oxygen to burn fuel.
