Shiny Metal Prism
I walk down the street corner where giant metal boxes hold papers for humans. Underneath one bright yellow box, I see a round mirror thing left behind. It is a discarded bicycle reflector. I pick it up with both hands. When I angle it straight into the afternoon sun, a sharp red beam fires across the gray sidewalk! It hits the dark tire of a parked bicycle like an energy spark from home. I tilt it left and right, directing the bright red light beam across the pavement. This small human lens can capture powerful solar rays and bend them where I point.
