Super Cool trick with a WATER bottle || Surface Tension | DIY SCIENCE |
Air and Water are two simple things we deal with in our day to day life and are very essential to human life. Like everything else in the universe, air is also made up of molecules. Air is present everywhere and the air molecules are constantly exerted a pressure on everything in the atmosphere and this pressure is called Air Pressure. We don’t feel the air pressure but it is present all the time. The higher altitudes we go the less the air pressure. Similar to air, Water is also made up of molecules. The molecules of the water on the surface of it is bonded more tightly than the molecules deep inside and this tight bonding is called surface tension. The surface tension of water is what holds the water molecules together is form a water droplet. Let’s do a cool simple Do It Yourself experiment at home using a water bottle to understand how air pressure and surface tension works.
