2C40.20 - Streamline Flow - Blow Out a Candle
Place a lit candle about 18 inches from your mouth. A 2 L soda bottle is partially filled with water. This is placed between you and the candle and then you blow directly at the bottle. The candle will be blown out on the back side of the bottle because the flow of air is directed around the curved sides of the bottle.
