Hydrostatic Pressure dependence on depth
Purpose:To show that the pressure increases with depth below the liquid level.
Procedure:The small disc is held onto the end of one of the vases by the string and then lowered into a large jar of water. The pressure holds the disc in place. Then water is added until the disc is free. Repeat the process with the other vases and note the level at which the added water frees the disc.
