How does a can of soda that has been shaken up.....?

Question

How does a can of soda that has been shaken up suddenly not explode if you tap the top of it a few times before opening it??

Well? What happened, Randy G? :P

Answer 1

u know when you drink coke or sprite from a clear glass you see all these little bubble on the side???

well when you shake a can all of these bubbles (they are carbon dioxide i think) come out of your drink and stick to the side and bottom of the drink. some but not all get to the top.

when you open a can all these bubbles rush out and so those bubbles on the side of the can and top push out the drink in foam.

when you tap a can you displace all of these bubbles and some float to the top. so when you open the can there are not many bubbles left to push out the liquid and so little or no foam

thats why people tap cans, to ensure there is not a huge foam explosion

Answer 2

That's a new one for me. I gota go try it now!

---------edit----

You are right, it worked (at least with Diet Coke). That is strange. I just learned something new today.
