This week, I will give you another challenge to ponder. Again, it is something that you have seen a million times, but probably never thought about. To try this, you will need:

- a faucet

OK, turn on the faucet, and look at the running water. Look at it carefully. Do you notice anything strange? No, it looks perfectly normal, right? Just as it always does.

Now look at the water again. Notice the size of the stream of water as it emerges from the faucet. Then follow the stream of water downwards. Is it the same size a few inches lower? No. As you get farther from the faucet, the stream of water gets smaller and smaller. How can that be? How can the stream of water get smaller?

Once again, you have a week to think about it. You are welcome to email your answers to me, or post them on my Facebook page.

Have a wonder-filled week.
