Image information: Nature's microfluidics: the abdomen of the African bombardier beetle (Stenaptinus insignis) contains a reaction chamber which receives a propellant (hydroquinone) and an oxidizer (hydrogen peroxide) from separate storage organs. These two chemicals combine explosively producing a boiling mixture of steam and corrosive liquid which the beetle is able to deliver on to the target through a steerable nozzle with an accompanying loud bang! [Image reproduced from Proc.
