A guy I used to work with told me about a trick people would play on each other when he was in college where they'd walk up to someone else's drink and drop in a tampon. (This was best accomplished when done while the person was holding the drink.)
The tampon would swell to the sides of the cup almost instantly and when the person next went to take a drink, they'd have a tampon in a cup.
If you took the cup and turned it upside down, the tampon would stay lodged in the cup as it had swelled to both sides.
If fluid accumulates in the pericardial sack, (more than 50 ml,) it's possible that it will have so much pressure that the heart can't move. This is called cardiac tamponade.
If you're studying for the 704 mid-term, this may have been useful to you.
I cannot verify any part of the above story, but it made sense when my friend told me. Then again, I'm very gullible.

Great way to remember this for a test, but that story has to be an urban legend. Unless it was a shot glass or an elephant tampon I doubt it would swell enough to keep from falling out when the cup was turned upside down. Definitely an interesting home experiment to test out though.
