Step 1: Get your materials
low-resistance material. (it means wire, dumbbell) I used rosin-core solder. because it was in sight and didn't move faster than me.
masking tape. (any kind of tape will work, but masking is easy to rip with your fingers)
nichrome wire. Can be bought in 10-foot rolls at unitednuclear.com, but I recommend looking for a spool of it on the internet (I used guage 38)
wire cutters and needlenose pliers help
