A:
Jessica,
That’s a good question for two reasons:
1) I don’t know the answer.
2) You can do a simple experiment to find the answer yourself.
Take two saucers and measure out exactly the same volume of liquid onto each (one tablespoon, say). Onto one saucer put plain tap water, and onto the other put water that you have already mixed with food coloring. You might try a whole set of saucers, each one with a different concentration of coloring mixed in. Put the saucers in a place where the temperature is even and there are no drafts. Now wait and see which one dries up first.
When you have the answer, please send us a message and we will post it here.
