Step 1: Materials
You will need:
The thickest rubber bands you can get.(size 109= $5-7 from most stationary stores)
Ideally a small pringles can but anything like that will do. (try to get something that is sturdy)
Scissors or knife
Masking or duct tape (optional, but will increase life of the rubber bands)
