Hey /sci/
Quick summerfag question.
I have just acquired a two-liter bottle of Canada Dry Ginger Ale.
My roommates can't be trusted with it if I leave it in the fridge.
So here's my question:

Is it possible to keep the Canada Dry cool by leaving the bottle in front of a box fan (pic-related) on the highest setting?

I doubt it will work, but I wonder what you guys think...

I will bump with random photos.

only if you wet the bottle.

No, it would keep it at the temperature of the air that is blowing. A fan will only accelerate cooling of an object that is higher than ambient temperature.

Put a block of ice or something else frozen behind the fan though, and that's another story.

wrong

so it will cool the moisture on the outside of the bottle, thus cooling the liquid on the inside? Any explanation why?

Could I drape a wet towel around it?

>> No.3382059

Make one of these.

that makes more sense. I have some Ice packs I could use for that. But come to think of it, that's all just really neurotic behavior, so I think I'll just go put it in the vegetable crisper.

Thanks /sci/

wet towel is fine.

block of wikipedia text follows:
Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures. As the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid, thus, decreases. This phenomenon is also called evaporative cooling. This is why evaporating sweat cools the human body. Evaporation also tends to proceed more quickly with higher flow rates between the gaseous and liquid phase and in liquids with higher vapor pressure. For example, laundry on a clothes line will dry (by evaporation) more rapidly on a windy day than on a still day. Three key parts to evaporation are heat, humidity, and air movement.

evaporation takes heat energy

put it in wet sand if you have any, and let the sand blow over the sand. shit gets reel cold. my friend lost his pinky because of frostbite once when we were at the beach when he reached in to get his beer. true story.

Secretly put laxitives in all of your food and let your roommates eat it.

One or two times of that and they won't be touching your shit anymore.

What kind of a fucktard would do that but not realize that the back is the most inefficient place to put it?

im not sure I follow the logic on it being bad placement.

also his later models are more effective
