Tents, Covers & Parachuts

A tent is a shelter, consisting of sheets of fabric or other material draped over or attached to a frame of poles and/or ropes. Some tent styles are free-standing, while others are attached to the ground using guy ropes tied to stakes (pegs). Tents were first used as portable homes by nomadic peoples, but today, their main application is for recreational camping. Modern tents are usually made of fire-retardant material. Covers are a large sheet of strong, flexible, water resistant or waterproof material, often cloth such as canvas or polyester coated with plastics such as latex or PVC. A parachute is a device used to slow the motion of an object through an atmosphere by creating drag. The parachute was invented in 1783 by Louis-Sébastien Lenormand. Parachutes are normally used to slow the descent of a person or object to Earth or another celestial body within an atmosphere.
