How to make a spark w a 9v?
Answer:
attatch two wires to the batterys plus and minus and then touch the other ends together.SPARK!
piezoeletric spark
Take a clean piece of steel wool and stick it on top of your 9 volt battery. Watch the sparks fly!
put it to your tongue
get a small piece of steel wool and touch it to the two contacts. I have heard this is a good way to start a fire with some tinder, if you're in a "survival" bind, and have both of those items.
you have to use a transformer step up voltages look for plans for a stun gun
Short out the positive and negative terminals. connect a wire to the negative terminal then connect a different wire to the positive then touch the two wires together. Works the same way as hooking up jumper cables to a car and touching the other side of the jumpers together.
I don't know how lame this is, but I was watching The Inferno 3 and they had to start a fire and they took steel wool (quite a bit of it, because a small chunk doesn't seem to work) to start their fire. Supposedly it will even work if both items are wet.
Air is a pretty good electrical insulator so the less air- the better. But with the small air gap, the closer the contacts and the low voltage spark will be hard to see. Try it in a dark room.
Get a big coil (like a spark coil from a car)
Connect the battery to the coil so that current flows through the coil.
Then quickly disconnect the coil
