If you shake a can of soda then open it it will explode because a lot of the carbon dioxide dissolved in the liquid wants to come out of solution all at once. This results because shaking the can distributes the small volume of carbon dioxide at the top of the can throughout the entire liquid vastly increasing its effective area and providing myriad nucleation points for the gas to leave the liquid. The pressure in the can does not rise from shaking it because it remains the same pressure used during carbonation. Tapping the can unopened should dislodge many bubbles within the can clinging to the can wall allowing them to collect again at the top of the can in a single bubble with far less surface area. This should help stop the soda from fizzing as much when the can is opened.

Well, a fizzy drink is simply gas trying to escape. Shaking a can increases the pressure in the can. Tapping it has very little affect. Tapping the can will produce more atmospheric pressure allowing the gas to want to escape more. So no. Tapping the can doesn't help.

Gas solubility increases with pressure. That's one of the reasons that the can is pressurized. By tapping on top of the can, your are increasing pressure slightly, thus increasing gas solubility, forcing the gas back into the liquid, decreasing the amount that gives you pressure when it "explodes"

yes by tapping on top of the can

tap it really hard it will stop the fizz and blow up in your face
