Light Beam

Today I was cleaning out my ducks pen, there is a hole in the top to drain rain water down into his little pool. It wasn't raining today but yet there was still something draining down into the pool. It was sunlight and it was only shining through that one little hole which made a perfect beam down into the water where it was then reflected all throughout the pool. I stopped and stared at it for a minute just examining what it was doing and how cool it was.
