I don't think it really works, but fluid dynamics are really strange!.

A side effect of tapping on the top of the can is that it delays opening the can, so it might help the CO2 settle a bit more in the interval, but that has more to do with the waiting than the tapping!.Www@FoodAQ@Com

I don't know if it really works but you tap the top of a beer can to keep it from foaming over!.Www@FoodAQ@Com

It is supposed to cut down on the foam!. I do it if I drop oneWww@FoodAQ@Com
