Which skill/trick did you try from the movies in real life? Did it turn out to work?

I did the forced saltwater drinking to induce vomiting after having ingested something spoiled a couple of months back. It actually worked.

What they didnt show in the movie was, it workes for both ends. Maybe it was too much salt, but after vomiting, explosive diarrhea followed.

Needless to say, I felt releaved.
