Question about modeling of Popping water balloon

I would also say that Rhino/Grasshopper may not be the perfect tool for the task. However, have a look at Flexhopper, which you could be used to simulate and spread fluid droplets and splashes: The splash simulation is part of the Flexhopper examples. Simulating the cracks in the ballon surface seems to be a very complex problem and would require a crack simulation (e.g. using XFEM). If you just want to create these ballon patches, then one approach could be to create a simpl…
