Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant. This is explosive dispersal. They produce seed pods which dry in the sun. As a pod dries, tensions are set up in the wall of the pod eventually causing it to split along two lines of weakness. Some plants have pods that explode when ripe and shoot out the seeds. Lupins, gorse and broom scatter their seeds in this way. When the seeds are ripe and the pod has dried, the pod bursts open and the peas and beans are scattered. Heat and dangerous reactions are the cause of many plant explosions. Gas leaks, most often caused by poor maintenance, result in a number of explosions each year. When gas leaks come into contact with a source of heat, they begin to expand and can explode.
