Natural Wonders

I went out to hang laundry yesterday, and I hung up some towels. The towels started heating up and the water started "steaming" from them.

I had to run inside and get my camera to capture it.Then when I was walking back inside, I noticed the windows of the house.

The ones on the main floor had condensation on them.

The ones on the second floor did not.

This is the main floor window...

This is the second floor window.

They are on the same side of the house, and there was no direct sunlight on either of them.

Just an observation to share.
