Removing the Disc:

First, remove the top. Then make a diagonal cut that nearly reaches the top disc edge. Gently pull the strip away so that its bottom corner has separated completely from the silver rim of the top disc. Gently, very gently, peel the can off like an orange peel. The last tiny bit can get left behind, so as you near the end of the peeling, slow down and be very careful to pull sideways, away from the disc in its plane, not down from it.

I show this being done with my bare hands, which is fine since I'm practiced at it; but you should try it with a thin towel over your hand as you pull — at least until you get used to it.
