AskUs: After dropping a can of root beer does tapping on the lid actually fix the liquid/gas equilibrium?

    Tapping does help to minimise the rush of bubbles from the liquid. After shaking there are thousands of micro bubbles attached to the side of the can. Tapping allow them to float to the surface and when you open the can the drop in pressure will allow them to expand but not bring the same amount of liquid with them as when they were still stuck to the side.
