Surface Tension and a Ping Pong Ball Experiment
In Atal Tinkering Labs ATL | No commentCan you place a Ping Pong Ball in the center of a cup or bowl and not have it move to the side? Answer is yes, if you break down the surface tension. Check it out! Placing the Ping-Pong ball at the surface of the water creates curvature in the water surface all the way around the ball. The surface tension will act to minimize the total surface area. Unless the ball is placed exactly in the middle of the cup Which is nearly impossible! There is an asymmetry in the surface curvature that will draw the…
