Does tapping on the top of a pop can really keep it from fizzing over?

Question

If you tap on the top of a pop can does it keep it from fizzing over? If it does, why?

Answer 1

No. Pictures where taken after an expirament. Please see this link. The bottom line is that if you don't want soda to spew out at you, let the can sit unopened for a while after it's been shaken. Time heals most things, especially when one of those things is delinquent carbonation just itching to have at you. Also, a chilled can of soda generally won't foam nearly as much as an unchilled one. On the flip side of that coin, a warm soda that's been given a good shaking makes for a suitable peace offering when the warred-with party is a pesky little brother.

Answer 2

I've always tapped the top of the can before opening it, but I had no idea it could reduce the fizz. I do it so the can is easier to open, because I have no nails (I keep them short for work and playing guitar).

But now that I think about it, I can't remember the last time a can fizzed over on me.

Answer 3

it style of feels to artwork in maximum circumstances. yet another element that works, once you're pouring the soda in a pitcher and it is going to foam over, place a fingertip interior the rim and it will stop it from foaming over.

Answer 4

It definitely does...I have no idea why, though. :) The tapping must neutralize it.
