| - | Fill apparatus as shown with coloured water. Updated on: 06/12/13 | + | Fill apparatus as shown with coloured water, and set up a close-up camera (if necessary) to closely compare the height of each column of water. Pascals principle dictates that the water should be level in each tube, but the capillary effect causes a visible deviation from this. |
