Humphry Davy, a chemist at the Royal Institution, found a solution to the problem in 1815. He discovered that a flame could not penetrate a wire mesh, meaning that any explosions could be safely contained within a lamp if some metal gauze surrounded the candle. Andy demonstrates in spectacular fashion exactly how this invention, which in many ways fuelled the industrial revolution, works, and celebrates a beautiful example of applied science in action.
