The squirting cucumber Ecballium elaterium shoots its seeds violently in a stream of mucilage when they're ripe.
The seeds can be shot up to almost 40 feet.
Researchers have studied how the squirting cucumber goes ballistic and found that the fruit detaches from the stalk, opening a hole in the base and seeds emerge at speeds of up to 66 feet per second.
The whole process of seed ejection takes about 30 milliseconds.
