Answer to Question #129 in Molecular Physics | Thermodynamics for little_kelly
At one end of the straw a bubble was blown and the other end of the straw was brought to the flame of a burning candle. Why will the candle flame be deflecting wayside at this?
The film of the bubble is always in tension and puts pressure on the air within; by sending a straw to the flame, the pressure of the film bubble will be blowing air through a straw and the flame will significantly deviate to the side.
