Have you ever looked closely on a water droplet? The water molecules at the surface of the droplet like to stick to each other more then they like to stick to air. This forms surface tension: the surface of the water acts like a skin around the droplet. We had fun exploring surface tension at our Girl Scouts meeting today. We started by placing water droplets on top of a penny with a small pippet. The water surface tension helps in maintaining a large drop of water on top of the penny. Next, we compared a water droplet to an oil droplet. The water droplet is round and tall, in contrast, the oil droplet spread on the wax paper. Water has stornger surface tension compared to oil. However, dete
