Pouring Light

I did a science experiment for homework called Pouring Light. You need a bottle with a hole on the side of it, close to the bottom, and a flashlight. You pour water into the bottle (while holding the hole). You have to go into a very dark room. The room has to be so dark that you cannot see anything.  You don’t need to be in a dark room. It just looks better. You shine the flashlight on the other side of the bottle across from the hole and release the hole. The brightest thing in the room should be the flashlight itself and the stream of water. When the stream of water is really bright it is called Total Internal Reflection. That is all I have to tell about my science project.
