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?

Question

What the title says. Pop means soda btw.

Answer 1

Am I allowed to ask follow up questions? I’ve always tapped my beer cans too. It made sense to me since they are also carbonated. But recently a friend made fun on me and said that is only a thing for soda. So does it work for beer cans too?
