how do you move a clam once it attaches?

[OCDP]

Removing a clam is not difficult at all, it's very easy. It may take a few minutes but it can be done without too much work.

What I do, and I am sure some won't agree with my method. I let the clam close up, then I gently start pulling (key word GENTLY) til' it starts to stretch a bit, then hold... and usually the clam will release, or you'll just pull it off. The important thing though is being gentle and slow. It has worked every time for me.
