Have you ever looked up at the night sky, saw a light moving and didn’t know whether it was a plane or a meteor? It happens. But if you had this flowchart, you’d be able to identify 90% of all moving lights in the sky. Roughly.
This flowchart by the League of Lost Causes is designed to teach you to use your deduction skills to correctly lights in the sky according to whether they move, their sizes and other characteristics. It’s even available as a poster, postcard and a mug.
