Beakman challenge: A paper wad is placed in the opening of a bottle. The challenge is to blow it into the bottle, but when Lester tries, the paper wad comes flying out of the bottle. Beakman explains this is because there is already air in the bottle and when you blow into it, the air has to go somewhere so it comes out of the bottle bringing the paper with it.
