Which fruits are exploding?

A plant must disperse its seeds to give them the maximum chance of becoming a new foot. One way to do this is to project them from an explosive capsule or pod. The laburnum and other plants of the pea family have pods. When a laburnum pod dries out, it splits, the two halves twist and scatter the seeds so that each new plant has room to grow.

Ecballium (donkey cucumber) projects its seeds by a jet of water from its fruits.
The internal pressure exerted by the water expels the seeds sudainly.
