thekid345 Posted February 2, 2008 Posted February 2, 2008 Yesterday i had an idea, but im not sure if it is really dumb, or genius(I think it is dumb). Anyways, why dont they make a microwave/oven that rather than heating things instantly, it makes food colder? :huh:

thekid345 Posted February 2, 2008 Author Posted February 2, 2008 Yes, but the freezer does not freeze things instantly..... :happy:
Septim741 Posted February 2, 2008 Posted February 2, 2008 I'm sure it's been done: a freezer that freezes things very fast. But it wouldn't be very affordable. Probably not happening anytime soon.
WoogieMonster Posted February 2, 2008 Posted February 2, 2008 There are "flash freezers" but they are not used for food, they are used for equipment that generates extreme heat like cryptology computers, gun barrels, etc. Ever seen your mother/sister/girlfriend polish her nails and then spray them with the this little can that dries the polish instantly? It's the same idea (and probably the same chemical) except it's big enough frostbite an adult mans whole leg in about 15 secs. We used to put six-packs of soda in it and flash them, they'd be nearly frozen after 5 seconds and at around 10 seconds the cans would explode and then Master Chief would beat us relentlessly.

Anyways, why dont they make a microwave/oven that rather than heating things instantly, it makes food colder? :huh:Because it's alot easier to put energy into most things rather than take it out. It's one of those physics things. And I'm pretty sure microwaves don't work like that. In order to cool something you need a space with a much lower ambient temperature than what you're placing inside. The rate of heat transfer is related to how well that object can retain heat and how much of a difference in temperature there is. Additionally, rapid freezing of things containing a reasonable amount of water may cause those things to get damaged as all the water molecules freeze and expand faster than the non-water components can contain those forces. If they are contained within something which doesn't allow for a release of pressure, they will explode.
Marcus Wolfe Posted February 2, 2008 Posted February 2, 2008 Water's a freak of nature: it's virtually the only substance that expands when frozen. When you freeze meat or vegetables, instant or not, the water molecules in the cells of the food expand and usually break the cell membranes. That's why fresh is always better than frozen.QUOTE(thekid345 @ Feb 2 2008, 05:13 PM) *Yesterday i had an idea, but im not sure if it is really dumb, or genius(I think it is dumb).

I ask you: What would you ever use it for?
thekid345 Posted February 2, 2008 Author Posted February 2, 2008 You're asking about the possibility of a domestic instant-freeze machine. I ask you: What would you ever use it for? For example, have you ever bought a 12 pack of soda, you get home its warm? Well, if you want it cold you put it in the fridge and wait a half hour. If it did it instantly, no wait!
Abramul Posted February 2, 2008 Posted February 2, 2008 For example, have you ever bought a 12 pack of soda, you get home its warm? Well, if you want it cold you put it in the fridge and wait a half hour. If it did it instantly, no wait!Use the freezer. Or just get a cup of ice.

I think you can see from WoogieMonsters post that flash-freezing soda cans is a bad idea.
