Q: Why does water melt ice?

A: We have this conversation every time you visit my laboratory.

That tap does not produce water. It produces nitric acid.

That's why there is a sign over the tap that says "Danger: Acid!"

And another sign that says "Not Water! Acid!"

You'll notice I added a new sign that says "Bill, Don't Drink The Acid!"

Please stop drinking the acid, Bill.

I don't have time to bring you back from the dead again. I have things to do today.
