This experiment was to see if water had surface tension. We places objects gently on top, some with hands others with rules or other tools. Many groups managed to get objects to sit on top of the water without breaking the surface tension. As you can see the water looks like it is bending around the objects.
We also did this experiment with milk and food colouring-this was a very interesting one as it shows how washing up liquid breaks the top layer of fat molecules on the surface of milk.
