eli5 – why does tapping the top of a pop can make it fizz less? Or is that just a myth I’ve been practicing for 30+ years?

Answer 1

Any can can be opened after 11 seconds. Shake the can as hard and much as you like. 11 seconds is what it takes. so tapping on the top is a way of buying time for the 11 seconds to pass.
