Visual representation of the development of an exploding granule and its disintegration by splitting into a new generation of granules. 1: A bright granule appears and expands rapidly. 2: Development of a decrease in intensity in the centre of the granule. 3: Dark centre expands and downflow velocity can be measured. 4: Intergranular lane structure becomes visible. 5: Exploding granule is completely separated into a new generation of granules or fragments.
