If that worked, dropping the can would dislodge all the bubble and - tada - no problem.

Geez, tapping the can is a not-quite-OCD ritual I've done forever. Now I remember the goofy idea that started it. Thanks FA!

I dunno, but I realized after I'd gone out to do some shopping this morning that I'd left four cans of iced tea in the freezer last night for rapid cooling. I'm sure you can all guess the end result of that memory lapse.

Tapping the side of the vessel seems to work for me.

Empiically (anecdotally):
- can unshaken, open steadily, no problem.
- can somewhat shaken, tap, open slowly, sometimes small bit of excess froth, sometimes just hissing gas.
- can badly shaken, just put it back in cooler/fridge for half an hour. You MIGHT be able to tap tap, open slightly and clean froth, then open fully, but why not just avoid that?

Tapping works, but only in a limited fashion. Background: years of carbonated beverage drinking/shaking.

"A 'tapped' can will have fewer of these 'deep' bubbles and so less liquid will be dislodged - and possibly sprayed out - than an 'untapped' can."

Confusing right?

Being a confirmed Pepsiholic, if the soda is hot, put it in the refrigerator.. hot liquids cannot hold gas in suspension.. for cold drinks, either can or plastic, firmly squeeze the container, hold pressure and shake it gently and slowly release the squeeze pressure.  wait a few minutes and slowly open the beverage, releasing the internal pressure.. drink.   irritates my neighbor, as he likes to shake the drink and see people sprayed..

I'm glad the three people who didn't believe this can now rest easy. I'd put this on the same level as people questioning whether phones not being in airplane mode automatically crash the plane.

Can shaken vigorously = opened and poured down the drain. Anything else results in flat soda 30 seconds after opening.

If you let the can settle, the gas goes back into the liquid and it's no different from a non-shaken can. If shaking ruined it, every one would be ruined before it left the plant.

I know it's mostly in my head, but once I know it's been shaken like it's a can of turtle puke green paint I just can't convince myself the carbonation is the same. I know, I know. It's silly.

Fun fact, this is basically the phenomena that causes the bends in divers. (With nitrogen in the blood acting like carbon dioxide in the cola.)

Pull the tab or twist the cap SLOWLY until you begin to hear gas escaping like a tire going flat, then wait until the sound stops.
 
2018-06-23 04:38:48 PM  
I assume that what's helping is not the tapping of the can, but the time taken to do it, thus allowing the CO2 to get reabsorbed by the liquid.

I drink a lot of wheat beers *cough bluemoon cough* that are secondarily fermented or unfiltered, and therefore have a little ring of yeast sediment on the bottom of the bottle. That's where all the goodness lies, so if I'm drinking straight out of the bottle at home, I flip it upside down and give it a few hardy swirls or shakes, then flip it right side up and give it a 1/2 dozen or so solid taps with my thumb. The trick is to twist/pop the cap as fast as possible and be ready to swig if there's a little rising foam. Works best when the bottle is ice cold. The warmer it is, the bigger the bubbles get and the less that little trick works.

The more science there is, the higher the likelihood of being blinded by it.

Excellent.   That should maybe deter him..  if he backs up after handing you the can, you know what's up.

The "Today I Found Out" crew tested it six months ago, and found no evidence that tapping the can was any better than just letting it sit there.

Yup. Let the pressure out slowly through a small crack and nobody gets doused. That's the only trick to it.

Tapping on the top does nothing.
Its the bubbles stuck to the sides and bottom that make it explode.
Flick it with your finger all the way around the sides to release the bubbles from the sides. Then when the air rushes out it doesn't bring the liquid with it.

Back in the 80's when Cherry 7uP first came out my brother convinced me that the cherry flavoring was at the bottom of the can so I needed to shake it up first to mix it. Results were predictable.

But the joke was mostly on him because the car our family had at the time was a Chevette. For those of you who aren't crappy car enthusiasts this is a Chevette.

Think of the smallest car you've ever been in and divide that size by 2. It was insanely small in that thing. Long story short Bro got covered with most of the soda because being the smallest of 3 I had to sit in the middle of the back seat so my dad could look out the rear-view mirror.

Anyway to tie the story back to the topic at hand, My mom screamed "WHY DIDN'T YOU TAP THE TOP AFTER YOU SHOOK IT!?" to which I replied "Why?"

You people want the science, here's the science.  If a ten year old boy hands you an unopened can of carbonated beverage, set it off to the side for a few minutes before opening it, maybe tap the side if you want to show off how much smarter you are than a 12 year old boy.  Convince them that tapping it on the side was the important part and encourage them to repeat the experiment with their face right next to the can.

Use this same method if anyone hands you an unopened can of carbonated beverage who used to be a ten year old boy.

If someone hands you a cold bottle of beer, and attempts to clink bottles by tapping the bottom of their bottle on the top of theirs, move your beer away quickly and punch them in the balls.
