beer goggles...

I'm still waiting for my real o-like goggles to get here, but in the mean time I've discovered that a standard brown bud light beer bottle passes only a very dim, diffuse spot when hit with 1W of 445.

Heres the spot at approx 1ft from the bottle, with the laser passing through sideways so it goes through 2 layers of glass. The spot is barely visible.

Also, if anyones ever aimed a laser into a beer, it is highly fluorescent, with a bright yellow beam through the beer.

I have, lol. It looks pretty cool.

Interesting. The glass must be acting as a filter....not sure if it would get the CE stamp of approval however

Yeah, most alcohol bottles block light quite well as to much light can inhibit the fermentation process.

We had a member blow his diode from a back reflection off the beer bottle he was pointing at.

Except... fermentation takes place in large vats, not in the bottle. :can:

I think its to protect the freshness from UV that would break it down otherwise, milk packaging does the same thing they're in soft white to yellow containers. Again I dont know what the UV damages in the beer or milk but that isn't something a googling can't fix cause now well.... I have to know since the question has been asked.

Oh, sorry I worded it wrong. The light can help other micro-organisms develop which can damage the end product. I read this somewhere but it may not be reputable and I am by no means an expert in that field...

Certain beers are fermented in the bottles.
