DIY: Liquefaction

The video tutorial demonstrates an experiment to understand liquefaction, a phenomenon where the ground loses its strength due to saturation, often occurring during earthquakes. The experiment uses sand, water, a ping pong ball, and a brick to simulate the effects of liquefaction. The tutorial explains the setup, execution, and observation of the experiment, highlighting the importance of understanding liquefaction for building safe infrastructure.
