Stopping Water From Expanding When It Freezes Doesn't Go as Planned

Water's volume increases by 10 percent when it freezes, but could that force break steel?

Here's a fun fact: When water turns from a liquid to a solid, its volume increases by about 10 percent. You might have already heard about this, but what would happen if you had the water in a container that doesn't expand at all? Would the water stay as a liquid? Or would it still turn into a solid without expanding? Stating that he has gotten this question a lot, The Action Lab tries to stop water from expanding while cooling it, but the experiment takes an interesting turn.

To do the experiment, he fills a steel container with water. Then, capping off the top with another steel cap, he completely freezes it solid and sees if it actually breaks or if the water — ice — can be contained inside.

If you're interested in watching such experiments, make sure you also check out this one where The Action Lab boils water with his bare hands or this one where he builds a bizarre 'floating table' held up by strings only.
