Sign in to playDrag a pressure gauge to different depths in a tank and read p = p₀ + ρgh. In the square pool, change the liquid and the gravity and switch the atmosphere on or off; in the chamber pool with wide and narrow sections, see that pressure depends only on depth, not on the shape of the container; in the mystery pool, measure the pressure and work out the density of an unknown liquid.
