bungee

Bungee refers to an elastic cord system used in bungee jumping and in various other applications. A typical bungee cord consists of multiple strands of natural or synthetic rubber wrapped in a woven fabric jacket. The rubber core provides high elasticity, allowing the cord to stretch markedly and absorb kinetic energy during a fall, then rebound. Cords are engineered to lengthen several times their original size while retaining strength, with specifications for working length, load rating, and safety factors.

The modern practice of bungee jumping traces its roots to the land diving rituals of Pentecost Island in Vanuatu, where vine or cord-like attachments were used in ceremonial jumps. The contemporary sport was popularized in the late 1980s by New Zealanders, notably AJ Hackett, who staged the first commercial jumps at Kawarau Bridge in 1988. Since then, bungee jumping has spread worldwide, featuring platforms, bridges, cranes, and towers as jumping venues.

Equipment and procedure typically involve attaching the jumper to the cord with a body harness or ankle straps, secured by carabiners and anchors to a stable platform. A backup line or multiple attachment points may be used. Operators conduct safety checks, monitor weather conditions, and ensure clear landing zones. Participants undergo briefing and must meet weight and health requirements; improper attachment or equipment failure can result in injury.

Beyond recreation, bungee cords are used for load testing, securing gear, and various industrial and theatrical applications, where controlled, rapid stretching and rebound are required.
