You have two plastic jugs filled with water. How can you put all the water into a barrel, without using the jugs or any dividers, and still tell which water came from which jug?

Highlight here for the answer: Freeze them first. Take the ice blocks out of the jugs and put them in the barrel. You will be able to tell which (frozen) water came from which jug.

I figured it out but I was efficient and only froze one.

Freeze the water in two different shaped jugs.

Problem solved.

First off, "water" is the common name for the chemical compound H2O. Ice is still water; it's still H2O; it's just another name for water in a solid state.

And just because there's no specific name for "molten steel" does not mean that the liquid form is somehow not still made of steel.

"Dry Ice" is a name for the solid form of carbon dioxide. But it's still carbon dioxide.

Let me put it this way: If I offered you \$10,000 to bring me a jug of water, and you brought me jug full of ice, would you be entitled to the \$10,000?

I don't like this solution. First, how are you supposed to pour ice out of the jug? Second, I challenge anyone to examine two blocks of ice and identify which came from which jug. I suggest that you should pour one jug into the barrel, allow the barrel to freeze, and then pour the second jug's contents in.
