What can be broken, but is never held

What can one catch that is not thrown

What breaks and never falls, and what falls and never breaks

Uncle Bill's farm had a terrible storm and all but seven sheep were killed. How many sheep are still alive?

What goes up, but never comes down?

What has a head, a tail, but does not have a body?

What did one campfire say to the other?

What becomes more wet the more it dries?

What provides the strength and power to walk through walls?
