Hi, i am doing a project at my school about water and i am stuck on a thought i had "Water in zero gravity is keeping a shape like circle because of the surface tension which creates something lika a film.. This film is destroyed if it comes in contact with detegrent.. What effect will that have in zero gravity?"
Please i need help on that one i am going to burn my brain if i continue trying to solve it on my own.
If water's surface tension is cancelled at 0 gravity..?

Hi supex,
Interesting question. What is your school project about? Water forms droplets to minimize surface energy. A liquid soap (which is mostly water anyway) will also form droplets for the same reason. So, first you would need to get two droplets - one of water and one of soap - to collide. I suspect that even if you were able to do so, you would only form more droplets. A sphere is the lowest surface energy geometry.

All the best,
