We're going to need another Timmy!
Same goes for freezing water, if you dont have enough coolant in your car for example. The engine block can crack if it freezes!
These are the guys Marsellus Wallace called after his run-in with Zed.
Look, Mr. Wizard, my blowtorch went off, I don't know why, and now you're helping us out of the situation. I'm cool with it, all right?
Breaking metal that way is amazing but...what's lowest temperature to heat metal to get steam and maybe excited electrons seems like most useful info. Definitely showed there's energy in them thar metal hot
Very nice experiment, finally someone who has confidence with a kid ! (Maybe even a bit too much).
Thank you this helped alot for my school
nice video, nice experiments as well, but not regarded for the explanation itself on why it happens. You should title the video as something a little more suitable. But anyways thanks for the video.
Hi,
I do sculptures and use welding rods as the main frames under my clay...like the rebar in a concrete wall only much smaller.
Can you please tell me what material, copper, aluminum, or steal ... expands and contracts the most when heated and cooled.
The material I use cracks from this expansion and contraction and I am trying to find the right metal for this job that contracts the least when these sculptures cool..
Thanks
God Bless

Aluminum expands the most, followed by copper, then iron, then steel.
Well, if you can find 4 candles I know how you can find the answer to this......
