You will need:
A 12 Fl. Oz. Red Bull can, a camera body cover to fit your SLR camera and a throw away camera lens. This lens came from a flea market and was actually free as it is a piece of junk. It is from a plastic camera that probably didn't cost more than $15 - $20 new.
You will need a hot glue gun or some good hard glue that will dry quickly.
Cut a hole in the body cap like you see here. I used a drill press and then just broke off the little pieces of plastic that didn't get drilled out. You don't need to get fancy with this as it won't show up in the pics you take.
Step 1: Step 1
The other end (bottom of can) needs to be cut like you see here because it needs to fit into the body cap.
