Oh my before I looked at the very bottom I kept going back up and was like you put toast in the toaster! And then I looked at the bottom and couldn't stop laughing <<< lol I thought toast at first, but then realized bread
I think this all the time. Try going in pitch black with a picher of water, a flashlight, and a bowl. As you pour the water in to the bowl shine the flashlight across the water. It will move sightly with the light.
