Bombardier Beetle

„The bombardier beetle has one of the most incredible natural defense systems on earth. Whenever threatened by an enemy, such as ants or frogs, this spirited little beetle fires a scorching jet of foul-smelling chemicals at its foe. This irritating burst of boiling liquid shoots out of its abdomen at more than 500 pulses per second at 212 degrees!

The bombardier beetle makes his explosive by mixing together two very volatile chemicals, hydroquinone and hydrogen peroxide. Whenever it’s annoyed by a predator, the bombardier squirts the stored chemicals into combustion tubes and violent explosion occurs that blisters the poor attacker.”
