Opening A Fizzy Drink Can
I have seen many people do this before, and for some reason I got into the routine of doing it also; more out of habit that anything else, as I was sure that it was a long shot that this tapping would actually do any good. However the other day I saw a program where they demonstraited this with a transparent can. Low and behold, it actually works! The "fiz" settles for a few seconds after the tapping, making opening safer and a lot less sticky!!!  I'm not sure about the science behind it - maybe someone can help explain? ___________________________________ Top Tips Forum - Friendly Help and Advice Technology, your Computer, the Environment, Money and Finance, Sports, Health and Fitness and Much More.

Quality!
Everyone I know does this! Its like a ritual. If you were an alien and you were observing people drinking from cans you would think its the proper way to do it! Its more fun going into supermarkets a shaking one can heinously then popping it back in the pile, leaving it to lurk until picked up by some poor unsuspecting punter.....

Ahh ha! I have an answer!! Apparently it works like this...
Drinks cans are pressurised so that the gas stays dissolved in the drink. Shaking a can causes some of the gas to escape, in an closed can it has nowhere to go and so it tends to cling to the metal sides, top and bottom of the can. If you open a can in this state then you release the pressure, and the compressed gas expands. Gas bubbles on the sides and bottom will "push" on the liquid as they expand, of course the liquid has nowhere to go except up and out of the can! All over your nice clean shirt!! Tapping the top of the can disslodges the bubbles from the sides and bottom and causes them to rise to the top. Now when you open the can the bubbles still expand, but the excess gas just escapes up and out of the opening itself, instead of forcing the liquid out!
