A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
It's simple. You just need 60 tons of lift and thrust. Aerodynamics help but you can make a brick fly.
