Does tapping a beer can actually stop it fizzing?

We all hate a can that goes too fizzy

Have you ever gone to the fridge to get a nice can of beer, cider or a fizzy drink of some kind? Have you ever lifted it out and looked at its dewey condensation and licked your lips at the thought of how your thirst would be quenched? Have you ever opened said can and for a brief second everything seemed fine but then a large portion of it fizzed up and out of the can all over your hand? Has this ever happened to you? Well, it's happened to us, far too many times. Some people swear that the only way to avoid such an occurrence from taking place, but does that actually work? We tried to find out, using the most scientific methods we could possibly find.
