Q: Does tapping on the top of sealed aluminum fizzy soda cans (like diet coke for example) reduce the probability of "explosive fizz out" - where soda fizz-out goes onto the floor, your socks, etc. Assuming that tapping the can top several times does have an effect (I do not know this to be true) the only explanation I can come up with: tapping removes any [tex]CO_2[/tex] bubbles on the side surface of the can. These bubbles act as condensation nuclei. Anybody know something about this? Am I all wet? not soda-wet... Everyone here assures me that can tapping works. I dunno.
