Inventor and all-around wild man, Colin Furze, has developed and demonstrated a pair of magnetic shoes that allow him to walk upside down along a metal beam on the ceiling.
Inspired by X-Men's Magneto, a character that can control metal by commanding the power of magnetization, Furze strapped two microwave transformers to the bottom of each shoe by connecting them to custom-fit metal plates along the soles. After strapping them on and giving them a test, his reaction is joy.
Each electromagnet is tested to hold 80kg and he has no trouble sticking to the metal. In a way, inventors like Colin are real-life superheroes, creating things and situations where we break the boundaries we've been told to live with. His ability may not be a result of mutation, like Magneto, but it's similarly effective.
