In 2008 I decided to build a jet engine, thinking that the skills acquired would help me develop a sub-orbital rocket launcher I had in mind while still being realistic. The task turned out to be an order of magnitude harder than I anticipated but it taught me the ABC of Engineering. After completing and testing the engine it was mounted on a mountainbike and driven around my town.
