Back raiding the kitchen again today - in the last 6 weeks I have spent more time in the kitchen than ever before - but not much cooking has been done.
@gavbrowne Hi Gavin - I put sunflower oil in a tall shot glass and then put drops of food colouring in. I tried looking from the side and above but all the drops were the same size and it was not very interesting. I then poured the oil from this glass into another one, let it settle and then poured the food colouring that was in the oil originally into the new glass. This time the balls of food colouring split up a so it looked more intesting. Maybe more information than you wanted :)
