Construction of a large metal sphere The construction of a spherical gas tank from metal. To take its spherical shape, the tank is filled with water, and explosives are placed in its center. The explosives are detonated, and according to Bernoulli's law the pressure of water during the explosion spreads the volume of the metal evenly.

A simple faucet, using physics The construction of a simple faucet in the countryside using air pressure in a bottle. Water flows out of the yellow straw if the pressure in the bottle is greater than atmospheric pressure. By moving the blue straw up, we reduce the pressure on the end of it and air leaks through it. Because there is a leak, the air gap is reduced under the lid and the water flows out. By moving the blue straw down, we increase the pressure at its lower end due to the water column and the water stops flowing.
