My invention - silent pop can

For those who have seen the movie Garden State can probably relate this post to silent Velcro. They can at least appreciate the financial potential of such an invention.
What I am proposing is somehow inventing a silent pop can. How many times have you been in a school lecture, a business meeting, a movie theatre and have been distracted by someone opening a pop can. Why can't someone invent a can that opens silently?
I have a free weekend coming up - I'll see what I can do.

Wish me luck!
