Why Does Tapping a Can of Carbonated Drink Stop Fizzing

AI Thread Summary
Tapping the top of a shaken can of carbonated drink helps reduce fizzing by temporarily increasing pressure, which aids in keeping carbon dioxide dissolved. When a can is shaken, the agitation causes more gas to escape from the liquid, increasing pressure inside the can. Upon opening, the sudden drop in pressure leads to rapid gas release, resulting in fizzing. Tapping the can may help to redistribute the gas bubbles and decrease the likelihood of excessive fizzing when opened. Overall, the technique is effective in managing carbonation release after agitation.

why does tapping the top of a can of carbonated drink stop it fizzing up after its been shaken?

This sounds like a good explanation... the question is: is it?
 
Why does it happen anyway??

I mean agitating the carbonated fluid makes the gasses dissolved in it escape, in this the reason? (I think it should have been, obviously this is the reason)
 
Carbon dioxide is dissolved at high pressure in the can and when the can is opened the reduction of pressure results in the gas coming out of solution.If the can is shaken beforehand the pressure is increased further due to the reason given by dE logics but with time the gas dissolves again.Tapping the can may reduce the time needed.
 
humm...trapping the gas will increase the pressure which will aid solubility with of the gas, as a result when compared to a case when the bottle was not blocked, the amount of gas that vaporizes should be more.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
