    Mythbusters did this and it works better if you tap the sides of the can instead of the top. You'll just look like an idiot doing it.

    Bingo. I haven't seen the episode but even after pouring a glass of carbonated drink you can tell where the bubble are. The sides of the can or glass have the most real estate for the bubbles to adhere to so the idea is to get the bubbles to the TOP where the air space is...

    Tapping the top of the can will not do anything more than picking your nose for 5 seconds before opening it. Even doing 10 pushups then opening it will be more effective than tapping the top lol! It's that time for the bubbles to get to the top after being disturbed is what is needed.

    Tapping the top will in no way assist the bubbles going to the top any more than the time spent doing it.

    How do you know it works? You can't test both ways on the same can...

    Because for the last 30 years there have been clear plastic bottles allowing you to see exactly how carbon dioxide rises since it's lighter than air. Do you see people tap the top of 2-liter plastic bottles before opening?
