Is it safe to supercool something in my house

[Someone502]

i don't know if this should go in physics but oh well.

First off, is it safe to supercool something in my house. Second, is it even possible. Third, how cold would i have to get it to supercool it?

Thanks.

What do you mean "super cool"?

 

[Someone502]

its when a liquid stays a liquid below freezing, but if it is disturbed even slightly it will freeze, very fast.

Oh, i dunno

Depends on what the something is. It's safe with water, not so with Gallium (this has nothing to do with your house - but Gallium is toxic)

Second, is it even possible.

Under the right conditions : yes.

Third, how cold would i have to get it to supercool it?

Again, this depends on what the "it" is. You have to cool it just below its freezing point. (I'm essentially quoting you here.) Different "its" have different freezing points.

After a quick google search :

1. Yes
2. Yes.
3. Unshaken, distilled water in a very clean glass bottle stored in a freezer for a few hours : it should crystallize when removed and slightly shaken if all goes well.

NOTE : You want to make the freezer temperature be just (a couple degrees or so) below freezing. Too low and it won't work.

A piece of foam padding, a thin sponge, or even a folded washcloth under the container will help dampen vibrations from the compressor and floor.

The disturbance from opening the refrigerator/freezer door will usually be enough the cause crystallization. So, it will freeze up before you can see it...unless you're really, really careful.
