These objects could be of any shape and size such as: a sword to cut a rope, chains to bind a prisoner, a parachute to slow his fall, and a disembodied fist to beat his foe. But they were always pure green in color and would vanish as soon as he stopped concentrating on them. Alan controlled these objects telekinetically. These conjured objects, later referred to as "constructs", would become the signature power of Green Lanterns in later decades.
