The seeds of squirting cucumbers (Ecballium elaterium), violets (Viola pedata) and touch-me-not (Mimosa pudica) scatter by bursting. When the seeds burst, it travels a considerable distance before coming to rest. The bursting of seeds are triggered by many environmental factors such as wind, rain and physical contact with an animal. If an animal triggers the seeds to burst, it may stick to the animal, enabling seed germination far away from the parent plant. This is important as growing very close to the parent plant will create competition for space, resources and sunlight.
