Simple electrolysis?

this is a science project that i will be doing this year. do you know where i can get the electrical wires and how do i place them on? plus, do you know if i need to get new pencils everytime i do this/ thanks

you can get electrical wire from the hardware store... to put them on... I'm not really sure the best way... you might just be able to wrap them around the graphite and tape them on. I'm almost positive you won't need to get new pencils, but try it out and see.
