The event involves designing and building a device known as a Scrambler that consists of an Egg Transport Vehicle (ETV) and an Energy Propulsion System. These functions may either be separate or combined into a single unit. The Energy Propulsion System consists of a falling mass that propels the ETV as quickly as possible along a straight track, with the ETV stopping at a specified distance along the track. The entire device, including the mounted egg must be shorter than 0.90 m in every dimension (length, width and height).
