Snapple bottles?

Asked by Trance24 (3311points) May 19th, 2008

When you get a snapple bottle ad turn it upside down and hit the bottom, it makes this loud cracking like sound. Why does it make that sound? I assumed it was because of pressure, but wanted to ask fellow fluthers their opinion.

it releases the safety lock which, when already popped means dont drink it because someone already opened it and it could be dangerous. basically a freshness guarantee.
