First of all - very cool that they were able to image this and work out the mechanical mechanism in such detail.

Second - the rupture event looks so violent but iiuc it’s actually highly controlled: - the rupture site is thinned early in the ovulation process - the expansion step pulls in fluid to the ovary (builds internal pressure) - the contraction phase restricts the cell volume (which also builds internal pressure) - the oocyte is launched out of the cell at a relatively high speed
