Hiccup away in 10 seconds
Here an unusual but very effective remedy for a hiccup:
You take a simple silver spoon (small or big does not matter) in the hand, looks concentrated for about 5 seconds in the recess of the spoon as in a mirror.
Then set the spoon aside and turn the spoon (with the recess down) during this movement.
I can not explain what's going on, but with nine out of ten people in my circle of acquaintances it always worked immediately and that was repeatable.
Just try it yourself, it really works.
