Instead of applying a deicing agent to strip ice from an aircraft's wings before stormy winter takeoffs, airport personnel could in the future just watch chunks slide good off without lifting a finger. Scientists report they have developed a liquid-like substance that can perform wings and other surfaces so slippery that ice cannot adhere. The slick substance is secreted from a film on the wing's surface as temperatures drop below freezing and retreats back into the film as temperatures rise.
