Pressure Under Water

Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membrane is connected to an open end manometer. When the drum is pushed under water, the pressure on the rubber membrane increases the pressure inside the tubing, causing the manometer fluid level to change. The kit includes a tall vertical container, rubber drum, tubing open end manometer and demonstration guide.
