Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag (or in the case of ram-air parachutes, aerodynamic lift). Parachutes are usually made out of light, strong cloth, originally silk, now most commonly nylon. Depending on the situation, parachutes are used with a variety of loads, including people, food, equipment, space capsules, and bombs.
