TAPPING A BEER CAN DOESN’T WORK
Do you tap the top of a beer can before you open it? Researchers at the University of Southern Denmark meticulously – METICULOUSLY – experimented with shaken and unshaken beer cans and found that tapping the top DOES NOT cause the beer to explode less. The theory behind the tapping is that: when a beer can is shaken, it causes bubbles to form in the liquid. When the can is opened, the bubbles rush to the top and cause the liquid to fizz out of the can. Tapping the can is supposed to cause the bubbles to release from the side of the can and rise to the top before the can is opened. But the research shows tapping the can doesn’t cause the bubbles to rise at all. Researchers had two sets of cans – one that was vigorously shaken and one that wasn’t. The cans were weighed before being opened and afterward. Some of the cans were tapped and some weren’t. The tapping showed no impact on the amount of liquid lost when the can was opened.
* And they performed the experiment again and again. And again. And again and again.
* In fact, they had to go out and get another two cases of experiment.
* On the other hand, secretly shaking a can before you give it to your friend is still hilarious.
* So, the takeaway is what? Switch to bottles?
* I was hoping for a breakthrough in the whole cancer thing, but whatever.
