Scientists have discovered that a certain type of carnivorous plant is able to catapult bugs into its gullet. A leaf covering the "pitcher" in a pitcher plant has a special coating on its underside. If a bug crawls on the underside of the leaf, that special coating ensures it can barely grip the surface. A water drop, a breeze, basically anything that causes the leaf to shake plops the hapless insect into the plant's waiting maw. Ain't nature grand?
