🤔 How it works ……..

How paragliding works ?

In paragliding launching and the landing is done with the wind. The wind is used as an airstream by running, being pulled or with the help of existing wind. The pilots are moved in a place from where they can be lifted. There are three different launching techniques: Forward Launch, Reverse Launch, and Towed Launch.

A paraglider works with airflow to create lift. Air flows over both the top and the bottom of the glider and meets at the edge. Aerodynamics predict that the pressure on the bottom of the glider is higher than on the top of the glider. This creates lift upwards.

😳Why❓❓❓

Why egg floats in salt water

Saltwater is denser than fresh water because of its salt content. The egg will sink in the fresh water because it has greater density than the water. The egg will float in the salt water because when salt is added to water its density becomes greater than that of the egg. That makes the egg float.
