I bet it went everywhere. I do that tapping thing on cans even though I know it makes sod all difference.

And it didn't go everywhere 'cause I'm not an idiot.

dented one end of it quite badly, then tapped top and bottom quite hard and then opened the can without explosion.
HARD PROOF.

Tapping on the top of a carbonated beverage can (or bottle) before opening it may help prevent the drink from exploding out of the can upon opening (although it might not be sufficient!). Sparkling or carbonated beverages contain carbon dioxide gas that is dissolved in the liquid by pressurizing the contents of the can. When the can is opened, the mixture depressurizes and the carbon dioxide comes out of solution, escaping as carbon dioxide gas. If there is liquid between the gas bubble and the outside of the can, then some of the liquid may be pushed out of the can with the bubble. The pressure gradient when the can is opened is greatest near the opening and the carbon dioxide at the top of the can escapes first.
If the can has been shaken, then the pressure differential inside the can during shaking will force some of the carbon dioxide out of solution to form bubbles. Some bubbles float to the top and some stick to the sides and bottom of the can. Given sufficient time, equilibrium will be achieved and the carbon dioxide will dissolve back into the beverage. If the can is opened immediately after shaking, it is likely that the beverage will spray all over the place, since some liquid from all parts of the can will be pushed ahead of escaping gas and out the can (hey, bubbles float to the top and these bubbles are under pressure too!). When the can is tapped before opening, bubbles adhering to the sides and bottom of the can may be jarred free. Assuming the can is upright, the bubbles, being lighter than the liquid, will float to the top of the can. Then when the can is opened, the bubbles are already near the opening, so they don't push through the beverage on their way out.

other than the fact that in reality it is utter bollocks.

also you totally copied and pasted that.

open can gas go boom. Spray kitty with sticky liquid.
Tap can make bad gas float to top of can.
Open can gas go boom but no sticky liquid cover kitty.
Kitty sad and go wank off commuters for 3.50 a go

Don't tap = bubbles on sides and bottom = pushes liquid out of can
Tap = bubbles come off sides and bottom = doesn't push liquid out of can

But she wanted a simplification of the crap that was said by Monty, so I gave her it. She's going to continue getting covered in nommy drinks anyway, 'cause I can't be bothered explaining it.

because the bubbles hurt my thwoat.

I thought of you the other day, during a conversation about sleepwalking. I have been unable to shake the term 'nomnambulist' ever since. This is neither a lie nor a joke, unfortunately.
