Sunbeam Painter

I spotted a shiny glass prism sitting on the low wooden windowsill catching the bright morning sun! When I tipped it with both hands, whoosh—a bright rainbow stripe leaped right across the white wall! I wanted to paint the whole corner, so I grabbed a blue plastic bottle cap from the carpet and propped it underneath to tilt the glass just right. Tap! The rainbow stretched into a giant arc across the bookcase. I hopped from red to violet across the wooden floor like playing carpet hopscotch!
