I have a challenge for you, /sci, to brighten up your night.
I realised I have no ice for my drink. By using kitchen utensils and household items how does one lower the temperature of a liquid?
I have one possible answer. Curious if there's some creative genius on /sci/ tonight who can give me a more innovative one.
GOGOGO!

A refrigerator is a household item

I use that

Lemon juice and baking soda. The reaction between citric acid and sodium bicarbonate is endothermic, makes a cold solution which you should be able to use to cool something else.

When you combine the ingredients, make sure to stir thoroughly.

Depends on the starting temperature. If it's hot, you can use a fan to reduce heat. If it's already at room temperature, I'm not really sure.

Tape knives along the perimeter of the glass and place infront of a fan.

[Anonymous No.1619382]

pour drink into pie pan, then direct a big fan directly at it. water will evaporate which can cool the liquid significantly below ambient.

also I hope your house isn't very dusty.

You could do it with a balloon. Inflate it, let it cool, then deflate it while making contact with your liquid. Of course, this is going to take a while....

go to store, buy a bag of ice, or go to freezer, and make some ice. simple solutions to stupid questions.

Don't be a retard. The point is to come up with creative solutions to the problem.

[Anonymous No.1619453]

Eh?

This is a genuine science related question. Sure, it's a little jokey, but it gets people thinking of new novel ideas to cool water and is clearly science related.

This is a breath of fresh air to the shit that's been on /sci/ tonight.

I have a NO2 dispenser in my room, so I'd probably just empty a cartridge into the water.

Pressurize it until it's a solid using your household utensils.

[Anonymous No.1619475]

Use a spoon to dig a small hole in your basement floor, maybe 2 feet deep. Throw a couple of butter knives down there until they cool to ground temperature. If your hole is sufficiently deep, they will get quite cool. Place knives in drink, cooling it.

Alternatively, just place drink directly in hole.

You might also try using the thermoelectric effect, and it will work, though this isn't going to make a big temperature difference. Essentially, a temperature gradient across a metal creates a voltage. You can reverse this (can't remember the name of the reverse effect) to heat one end of a metal rod and cool the other. This is not the heat that is generally generated by resistance alone--it's a different effect.

Anyway, you could get a battery, a metal utensil, and another metal utensil with a different composition. Hook one end of the battery to one utensil, the other end to the other, and touch the utensils together. One utensil will heat and the other will cool. Place the cooling one in your drink.

Stealing from this, the dissolution of sugar in water is slightly endothermic. So just add sugar! If you don't want sugary water (for some strange reason), fill a casserole dish with water and place your cup in it, then add sugar to the casserole dish.

wow, that is going to taste like SHIT.

It's going to be crazy bubbly, too.

You never drink the reaction solution, dummy.

GRAB WATER WITH HANDS

CRUSH WATER WITH HANDS

INCREASE WATER PRESSURE

ICE

BITCHES

[Anonymous No.1619574]

>>1619552
actually that would increase the temperature


If the liquid is a carbonated beverage then you could shake out all the fizzies and that will lower the temperature slightly. I rarely refrigerate cans of soda for this very reason.

[Anonymous No.1619615]

If it's cold out, take a piece of metal outside until it's cold. Then, put the metal in contact with the glass.

Or "use MACPHERSON", as captcha told me

[Anonymous No.1619654]

Hmmm...

Run the beverage through a copper tube. spray the tube with alcohol, and expose it to a fan. This should cool the drink down.

[Anonymous No.1619674]

Turn on toaster.
Place hands on sides of toaster.
Remove hands and place in glass of water.

It feels cooler than it did!

[No.1619679]

I don't know if this could be considered a household item but I have a vacuum pump at mine. So theoretically I could build a vacuum chamber put the glass in and turn on the pump. As the pressure in the chamber decreases so does the boiling point of the water till the water will begin to boil at room temperature. Since boiling is waters way of releasing thermal energy the water in the glass should be significantly colder. Provided it doesn't all boil away first.

Stick it in the fridge, dumbass.

I like these two.

If you have a BBQ, put the gas canister in a bucket of water along with ur beverage, then cook up a mean feed. As the gas changes states from liquid to gas it will take energy from the water that its in therefore making it colder.
I have actually tested this and if you have 4 burners going for about an hour u can cool the water by about 7 degrees, obviously depending on ur BBQ and whatnot.
