Steel Wool
Cotton Balls
9 Volt battery
Steel wool comes in several grades. You will need a fine (thin) grade for this to work. I have chosen grade 000. Other grades may work as well. I found my steel wool in the painting section of my local Miejer store for three dollars. I'm sure you could also find this at places like Wal-Mart, K-Mart or any hardware store.
The cotton balls can be found almost every where, I paid one dollar for a giant bag at my local dollar store.
The 9 volt battery can be found most anywhere as well. I paid three dollars for mine.

Sorry, I should have started with "thanks, and very cool," since it is.
