Jellyfish stingers reach an acceleration 50 times faster than that of a bullet as they are ejected from stinging capsules under high pressure. Uri Shavit at Technion-Israel Institute of Technology has developed a new mathematical model to explain this incredible mechanism which will help to make us better prepared to protect swimmers from jellyfish stings.
