When I was 15, I made a small model of an aircraft and a wind-tunnel to explain the concepts and principles of flight, for my science project. I thought this would make me popular among the "cool" kids. It did, temporarily. Some other kid ended up making a motherfucking model rocket fuelled by the sudden release of pressure from a heavily shaken Coke bottle. I still got first place, but the bitches in my school were awestruck by the other jackass. Well, look who's an engineer now, you bastard!
