This project is not very useful, but it's still fun.

You will need these tools:

_Alligator clips

_A power supply that can deliver a considerable amount of current (an ATX power supply is totally fine)

You'll also need these materials:

_Aluminium foil

_A paperclip

Connect a piece of foil to the ground an a unmade paperclip to the +12 volts.

Now, just just need to touch the edge of the foil with the paperclip and watch small plasma-arcs forming at the contact point. And if you need to cut a precisely shaped hole in a sheet of foil, this thing can even be useful! :D
