A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.

An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

Holy shit

I put one in an hour ago, thanks 😂

[–] Subnet64@lemmy.world 40 points 10 months ago

OMG. Thanks!

If you have an ice maker and a small cooler it’s way quicker to put them in the cooler and cover them with ice and water. You know, if you have a cold beer emergency and don’t want to wait for the freezer to cool it down. 5 minutes is plenty.

[–] polonius-rex@kbin.run 24 points 10 months ago (2 children)

add salt and it should cool quicker

[–] zero_spelled_with_an_ecks@programming.dev 15 points 10 months ago

Add lime and you still shouldn't drink that ice water.

[–] brbposting@sh.itjust.works 6 points 10 months ago

Salt + stir, I recall

Not sure if covering beer in a wet paper towel before it goes into the freezer is a legit method or not

Of course would limit both of these due to unnecessary waste

[–] fuckwit_mcbumcrumble@lemmy.dbzer0.com 10 points 10 months ago (1 children)

You can also just wrap them in a wet paper towel to get the same effect. Or even better wet paper towel with some ice on top.

[–] BarrelAgedBoredom@lemm.ee 2 points 10 months ago

You beat me to the punch. It works great! 15-20 mins tops and your beer is ice cold

[–] numberfour002@lemmy.world 15 points 10 months ago (1 children)

I've tried all the "quick chill" methods I've heard of, but none of them work as quickly or as well as the icecream maker method. Watered down ice with some table salt. Set your unopened beer into a slurry like that, and in about 20 - 30 minutes, it's surpremely cold. None of the "5 minutes and it's ice cold" methods work as well or as quickly to be honest. At least not in my climate and in my experience.

[–] cordlesslamp@lemmy.today 10 points 10 months ago* (last edited 10 months ago) (1 children)

There's a cheap machine that dip the can in ice cold water and spin it really fast. It cool the can down to <5°C in less than 3 minutes. I think it'll work even better with your salt method.

Edit: changed the time and temp because it works even better than my memory.

By spinning the can in ice water, it increases the rate of transfer of heat energy from the drink in the can, to the can itself, to the ice water. It's like how stirring the ice in a cup of not-cold water will melt the ice / cool the water faster.

At a molecular level, you would see an increase in the number of collisions between ice molecules and liquid molecules. The collisions must occur for heat transfer to happen, so more collisions = more cooling. It is also the same reason why a heatsink can draw more heat from a processor when a fan blows air over it ~~(until the air is saturated with heat)~~.

[–] Pentel@lemm.ee 3 points 10 months ago (2 children)

How can air get heat saturated? i followed you thus far but its not like humidity, you can always add more heat the question is if a faster flow decrease the time for each molecule to absorb the heat/motion and thats why sometimes higher flow wont yield in better cooling

[–] TheOakTree@lemm.ee 3 points 10 months ago (1 children)

Sorry, saturation is not the right word to describe it. I was thinking of the ice/water analogy and I mistakenly applied it to my heatsink analogy.

The correct limit to the heatsink analogy would a function of the thermal dissipation of the heatsink (material, surface area, thermal resistance) and the qualities of the surrounding fluid (ambient temp, flow, etc). Honestly, my comparison between the ice/water example and heatsinks is not good. It is only appropriate in reference to the "molecular collisions" concept I mentioned before.

[–] Pentel@lemm.ee 2 points 10 months ago

F me I forgot the beer in the freezer

[–] SpaceCadet@feddit.nl 2 points 10 months ago (1 children)

How can air get heat saturated? i followed you thus far but its not like humidity, you can always add more heat

When the temperature of the air and temperature of the object you want to cool reach an equilibrium, no heat gets transfered anymore.

[–] Pentel@lemm.ee 1 points 10 months ago

That is equilibrium not saturation.

You just need a way to spin the can. Probably works better if you speed it up and slow it down or reverse direction repeatedly.

[–] TurtleJoe@lemmy.world 1 points 10 months ago

Just use your hand. If the beer is in a bottle, leave it so the neck is sticking out of the ice water and spin it that way (this also works very well for wine.) If it's a can, stick it in vertically, and spin it for 30 seconds at a time or whatever you can stand.

Even if you aren't constantly spinning it, it will still get cold much faster than any other method. I've worked in bars and restaurants for 15 years, and this is my go to, in case of emergency method for chilling beverages.

[–] TheOakTree@lemm.ee 1 points 10 months ago (1 children)

The main reason spinning a can works is because it induces convection inside and outside of the can, which contributes to more collisions and better distributions of collisions. If the warmest soda is in the middle of the can, the cold molecules near the can walls will reach a temperature similar to the ice bath and thud the rate at which heat is transferred becomes stunted.

For lettuce, you'd have better luck finding a way to pass cold water between the leaves, much like having fins on a heatsink (surface area).

[–] cordlesslamp@lemmy.today 1 points 10 months ago* (last edited 10 months ago)

Neat explanation, thanks.

I've seen a video explain how it works, plus an explanation on how it doesn't make carbonated beverage cans explode when opening like if you shaken it. But I can't seem to find that video.

[–] cordlesslamp@lemmy.today 1 points 10 months ago

Something like this

https://youtu.be/6WqZdMLkdCI

I think you can get it as cheap as $10-$15.

[–] southsamurai@sh.itjust.works 14 points 10 months ago

It was a cider, but thank you :)

No bullshit.

[–] Kolanaki@yiffit.net 12 points 10 months ago

Nah it's cool. I only have tequila in there. It won't freeze.

[–] supertinkers@sh.itjust.works 12 points 10 months ago

Thank you, almost forgot.

[–] Subnet64@lemmy.world 12 points 10 months ago

Crap. Now I have a can of beersickle.

[–] shalafi@lemmy.world 11 points 10 months ago

Just got mine out 5 minutes ago! And the one I left overnight.

[–] cron@feddit.org 10 points 10 months ago (2 children)

Or put it in the fridge a few hours before you want to drink it, and not only five minutes or so.

[–] lightnsfw@reddthat.com 10 points 10 months ago

But that requires a level of forethought and planning I'm simply not capable of.

[–] fuckwit_mcbumcrumble@lemmy.dbzer0.com 4 points 10 months ago

That's assuming that you haven't already burnt through your supply of fridge beers.

[–] PunnyName@lemmy.world 9 points 10 months ago

I'm homeless. I ain't got beer or freezers.

[–] RickAstleyfounddead@lemy.lol 8 points 10 months ago (1 children)

Remind me after 10 hours I've chips

[–] The_Picard_Maneuver@lemmy.world 8 points 10 months ago (1 children)

Hey bro, remember you have chips.

[–] RickAstleyfounddead@lemy.lol 3 points 10 months ago

Lol thanks

[–] Tb0n3@sh.itjust.works 8 points 10 months ago

This is why you never do it. Just too big a risk.

[–] SpaceCadet@feddit.nl 5 points 10 months ago

Pro tip: set a 40 minute timer on your phone as soon as you put the beer in the freezer.

[–] Sam_Bass@lemmy.world 2 points 10 months ago

Yeah if you pull it out gently you can open it in the sink

[–] x4740N@lemm.ee 2 points 10 months ago (1 children)

I don't drink beer and rarely drink alcohol

[–] Psythik@lemmy.world 4 points 10 months ago (1 children)

What's your drug of choice, then?

[–] z00s@lemmy.world 1 points 10 months ago

You're doing God's work, OP
