At present we are focussing on observation.
In this experiment we dropped a little bit of dishwash liquid on top of some drops of food colour in a tray of milk. We watched as the colours swirled around the dish. We found out that the dishwash liquid was trying to gobble up the fat particles in the milk and we could see the milk moving away as we had coloured it. It did not work with water because there are no fat particles in water!
