Noxious chemicals, water, and steam -- at a temperature of about 212 degress Farrenheit-- are sprayed onto an attacker.
The chambers are less then a sixteenth of an inch long, yet the beetle can change the speed, direction, and consistency of it's toxic spray.
Researchers have studied the bombardier beetle to learn how to develop more effective and ecologically-sound mist systems.
They have discovered that the beetle not only uses one way-inlet valves to allow chemicals into the reaction chambers
but also has a pressure- relief valve to expel them.

Engineers hope to use spray technology based on the bombardier beetle in car engines and fire extinguishers,
as well as in medical delivery drug devices, such as inhalers.
