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

I read in a fun fact book a couple years ago that it’s not the tapping that helps the fizz settle, but the time it takes. Tapping a soda can actually make it fizz more, but waiting a few seconds gives time for the soda to calm down.
