Bernoulli's Principle

Bernoulli's Principle is the correct answer for our latest poll. The air rushing across the surface of something causes a lower air pressure. That's why carpets dry quicker when high-speed air movers are set up after a carpet has been cleaned. The difference in air pressure allows the moisture to evaporate quickly thus slowing or preventing "wicking" which is deeply embedded soil reappearing at the tips of the carpet fibers.
