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

Somewhat true. The thing you’re doing isn’t what you think you’re doing.

It is your time delay that makes it fizz less, not the tapping.

If tapping makes the brief wait more bearable, tap away.
