An even better zombie alert sistem!

This us a relatively simple trap that can be used without the thing activating it knowing. you will need two pieces of cardboard, , a light bulb, a C or D size battery, two pieces of crush-able foam, two foil squares, and insulated wire with bare copper ends, also you will need adhesive tape. tape the foil squares to the cardboard pieces, then tape the wire to the foil so that when pressure is applied the wires touch. hold the two pieces of cardboard apart by two pieces of crush-able foam. create the same circuit as the tripwire. When pressure is applied, the wire ends touch, completing the circuit, thus lighting the bulb and giving you a warning. 1  out of 3 found this valuable. Do you?
