Very nice article that makes the point of explaining how dedicating time and resources to research seemingly worthless things can actually be useful for many other purposes.

What do scientists know? The floating peanuts are clearly a message from God that you shouldn't fill beer with carbon dioxide, or if you do, you should call it lager or perhaps fizzy beer.

I have some beer and peanuts so this evening I will do some research. All for science if course.

It took "scientists" to figure this out? Don't they have better things to do, like fix climate change??

Please re-read the article. This discovery has industrial applications such as for mineral extraction from ore.

Sigh. Not a beer drinker I take it? What do you think all those bubbles are when you pour out beer into a glass? It is a natural part of the fermentation process.

I was joking somewhat. While fermentation produces CO2, most of it will disappear into the air. There is a big difference between "real ale" and gassy beers that are re-carbonated after filtration.

I should probably do a test to see if there is a different behavior when dropping peanuts into different kinds of beers. (But will I remember the results?)
