Also known as Mariotte's Cylinder, this simple device offers a famous and convincing demonstration of the increase in water pressure with depth. The cylinder has three equally spaced holes in its sides. When the cylinder is filled with water, the outflowing streams follow three different trajectories, governed by the water pressure at the depth of each hole. Made of Sheet Metal cylinder 400 x 60 mm (h x d) with a wide base ensure stability. |
