The Drip Temperature experiment!

Which runs faster: hot or cold water? Hot runs faster because you can’t catch a hot, but you can catch a cold.
What Happens: The pin holes on the bottom of each cup are the same size, you’ll see that the hot water drips faster then the cold water. If the cold water is cold enough it may even stop, like it did in this demo. The cold actually stop dripping for a couple seconds.

Why: Molecules exist although we can’t see them. The molecules in hot water move faster then in cold water. The faster the move, the easier it is for them to slip past each other.. That is why hot water is more likely to drip than cold.

Molecules are so small that it is almost impossible to see them, even with a powerful microscope.
