Drip Timer courtesy of the Jolly Roger

Another method of time delay for explosives that are detonated by

electric means, is the drip timer. Fill a 'baggie' with water and

then add as much salt as the water will hold. Seal it, leaving some

air inside. Then, tape the two contact wires from which the circut

has been broken, to the inside of a large cup. Place the baggie on

the cup. Poke a hole in the top of the 'baggie', where there is

air, and then make a hole in the bottom to let the water drain into

the cup. As any Einstien figures, the salt water level in the cup

will eventually cunduct electricity at the moment both wires touch

water, thus completing the circut. I have yet to try this timer

out, and I got the plans from a total idiot, phreaker nonetheless,

and doubt it would work with any power source under 12v.
