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

My wife always taps the top of her Coke cans before opening.

I never tap the top of my beer cans before opening.

I don’t think tapping on the top of the can does a damn thing. Neither of us have had cans explode on us unless they were violently dropped just before opening.
