How was Pascal able to destroy the barrel with the help of a mug and a pipe? What is hydrostatic pressure? How to determine the force of pressure on an area? What is the hydrostatic paradox?These and other questions are answered in the video.

Pascal’s barrel is the name of a hydrostatics experiment allegedly performed by Blaise Pascal in 1646. In the experiment, Pascal supposedly inserted a long vertical tube into a barrel filled with water.
When water was poured into the vertical tube, the increase in hydrostatic pressure caused the barrel to burst.A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.
Pressure exerted on a fluid in an enclosed container is transmitted equally and undiminished to all parts of the container and acts at right angle to the enclosing walls.The pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid.
