A Mouse Trap
A simple mouse trap can be made of two lengths of steel wire. The spiral wire is 1/16 in. in diameter and the center wire is of larger size. The trap is set by pulling out the spring and catching the ends on the bends A and B. The bait is tied on at C. When the mouse puts his head through the coils and pulls the bait, the springs are released and his head is caught between the coils.
