What tree has fruit that explodes?
Sandbox tree fruit looks like little pumpkins, but once they dry into seed capsules, they become ticking time bombs. When fully mature, they explode with a loud bang and fling their hard, flattened seeds at speeds of up to 150 miles (241.5 km.)
What is the plant that pops?
One common weed, the popping cress, has evolved a way to launch its seeds in an explosive burst that gives the plant its name. Its seeds are encased in a slender oblong pod.
