Light in a Glass

Regular Flashlight

I was playing with my MagLite today and I wanted to make another lens for it to see how the light will be distributed. I decided to put an empty glass in front of the flashlight and the light was distributed all over the place. The light entered the glass and was reflected and refracted all over the glass. The light beam on the wall was larger but the light was weaker. I also realized the light created a bunch other rings of light and some light rays were on the ceiling and floor. It just interesting how the glass distributes the light anywhere the light can go.
