Squirting cucumber - Ecballium_elaterium

"Ecballium" is a genus of flowering plants in the family Cucurbitaceae containing a single species, "Ecballium elaterium", also called the squirting cucumber or exploding cucumber. Its unusual common name derives from the ripe fruit squirting a stream of mucilaginous liquid containing its seeds as a means of seed dispersal, an example of rapid plant movement.
