Finger in the ears: the hiccup disappears immediately

You will humiliate me in your comments and laugh at you.

This tip works but really - no joke:

If someone hiccups, you need two more people. Each of these people has to put an index finger in an ear of the person with hiccups. (Does not have to be plugged in properly - just a bit). While the person has a finger stuck in each ear, she drinks 3 mouthfuls of water.

Result: the hiccup is gone immediately!

Background is probably a highly complicated process of what has to do with psyche, the influence of other people on their own perception and distraction.

Try it!
