Viscosity of fluids effect on it's splashes?

[PinkOcto]

Hi all,
i'm doing a research essay on how the viscosity of a fluid affects it's splashes.
i'm currently stuck and do not know how i should approach this theoretically. i have no problem with the practical (filling up balloons with the fluid and dropping them from a height to see the splash distribution).
also, I'm wondering how i could quantify this splash distribution?

You might want to check Wikepedia for starters.

which gives a few links to Lei Xu and Wendy Zhang and their research.
