Hot water is like hot air, you know.
It rises to the top.
The first few moments that liquid boils, all the heat is at the top.
If you stir it with your hands, the cold water is mixed with the scalding liquid, and it is cool enough for a human hand to stand.
And what about the hot molten metal?
Does that rise, too?
You see, the metal would have to reach a very high temperature before it would melt at all.
Oh, Rhoda, no, no, no.
But why not?
Because, Alan, that isn't molten metal at all.
It's mercury.
It just looks like metal.
So that's how you did it.
Well, Blackstone, what is it this time?
Just a simple little trick with matches.
Here, here's a box of matches right here.
First, you empty the matches from the box on this table.
No, it's just a little different than that, Rhoda.
Just a little different.
