The Hand of God is a 12-foot tall hand-beaten copper sculpture of a woman's hand which creates a plumes of flame 30-100 feet (10-30m) tall.
The Hand is a liquid fuel fire effect; pressurized fuel is controlled through high-speed pneumatic solenoid ball valves. Four of the fingers operate with 1/2 inch valves; the pointer finger has a 1-1/2 inch valve for a bigger jet of flame. The Hand can create more than one plume of flame at a time, and operators can vary the sequence for each performance.
A range of liquid fuels are used combined with transition metal salts to create colored effects. All of the mechanical elements and control systems are hidden inside the Hand, but can be viewed through a copper portal from the back. The propane igniters can stay lit for hours
