They filmed the seed dispersal using a high-speed camera, which captured up to 8,600 frames per second. They then measured the fruit and stem volume both before and after dispersal, performed indentation tests, took CT scans of an intact cucumber, and monitored the fruit with time-lapse photography in the days leading up to the seed launch.

But take a closer look at the plant, which grows in dry, barren areas in the Mediterranean, and you’ll find “an extraordinary thing,” said Chris Thorogood, a botanist at the University of Oxford Botanic Garden and Arboretum.
