In this video we will try to show a physics interesting experiments. we will float a needle in the water. It occur for surface tension. <br /> ✻ What is SURFACE TENSION? <br />Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible. Surface tension allows insects (e.g. water striders), usually denser than water, to float and stride on a water surface. <br />In this video we give a experiments about this. You will also try it at home. <br /> <br /> <br />◉ FOR MORE READ THIS IN BANGLA:- https://bn.wikipedia.org/wiki/%E0%A6%AA%E0%A7%83%E0%A6%B7%E0%A7%8D%E0%A6%A0%E0%A6%9F%E0%A6%BE%E0%A6%A8 <br /> <br />✔Video Topic: Needle float in water <br />✔Name of series: SCIENCE EXPERIMENTS(BANGLA) <br />✔Watch all video on this series:- https://www.youtube.com/playlist?list=PLjBJfzdiEwdqicMwM1SIILa7bcUZQYj6Y <br />✔Name of Speaker: Fuad Hasan Rabbi <br />✔Content maker: Fuad Hasan Rabbi <br /> <br />▼ Social media Link ▼ <br /> <br />►Facebook Page:- https://www.facebook.com/passionforlearn/ <br />►Facebook Group:- https://www.facebook.com/groups/passionforlearn/ <br />►Youtube Channel:-https://www.youtube.com/channel/UCjDVYiBmUFeBM0nQOTBnq5w <br />►Dailymotion Channel:-http://www.dailymotion.com/passionforlearn <br />►Twitter:- https://twitter.com/passionforlearn <br />►Pinterest:-https://www.pinterest.com/passionflv/ <br />►Google+ :- https://plus.google.com/116414170130897389553
