This trick is hard to get right, but it works - you just have to know the sound of the ping. It works with any can of soda etc...

Carbon dioxide is dissolved in the soda. depending on conditions, it can be in what is called a metastable state. This is a fancy word for unstable. If this is the case, there is too much CO2 in the soda, so the excess will release when the pressure is lowered by opening it. By "pinging", you create sound waves that induce CO2 to form int bubbles that can be released before you open it. You will still hear the release of the gas, but since it isn't coming from within the liquid, it doesn't cause the spray.

The idea is that the vibration collapses the bubbles of carbon dioxide, so that what escapes is just carbon dioxide rather than foam. I'm not qualified to address your sanity, your Coke addiction, or the relationship between the two :-)

I don't believe that really works.
