You can use this same principle to open a bottle of wine without a corkscrew.

I don't know but I'll tell you what's funny.  If someone does that to you in the car, put your thumb partly over the drink hole and spray beer all over the car.  The owner of the car wasn't happy, but it makes me smile to this day.

wikihow fail. Champagne bottles don't need a corkscrew. Anyone that bangs on a bottle of bubbly shouldn't be allowed near it in the first place.

So you can get the same effect with a laser.... Wow, imagine doing this remotely to the douchebag hitting on your date while you're in the bathroom.

When I hit the beer hard, it usually hits back.

In college, we called this "buttfarking" someone else's beer.

Looked briefly at the article.  How do you make the beer go to foam with a laser?

Done...so this CAN be done with a laser, but not with your typical off the shelf laser pointer across a bar as alluded to above.

in the brewery, we call this "fopping" the bottle.

if you are hand bottling pre-carbonated beer you do it via counter preasure filling where the bottle is preasurised to a few bars below the fill tank preasure so that the suspended CO2 doesnt come out of suspension. after the bottle is filled, you present it to the bench capper, place a cap on the top of the bottle, bring the capping cup down and hold in place.

now the fopping part... take a wrench or screwdriver and tap the side of the bottle. the vibrations agitate the suspended CO2 causing a foam over, but you are holding back the eruption with hand preasure.
let up a little bit of your holding preasure and let a squirt of foam spray out from the cap then immediatly cap the bottle.

rinse the bottle, put it in the case and repeat as necessary.

the purpose of all this is so that you are capping on foam, and that forces all the air out of the bottle.

on automated machines we'll either use a jet of water or co2 to fop the beer at the neck of the bottle right before it hits the capper.

Ha! Yes. If this could be done with an OTS laser pointer, the manufacture of those things would be more sanctioned than chemical weapons.

Would a 1W blue laser do the trick?
