How water skin forms, step by step
1. Take a crystal dish and fill it with water.
2. Place several chopsticks forming a kind of star in the center of the fountain.
3. With another toothpick, take a drop of soap and pour it in the center of the container. You will see how the chopsticks separate and begin to float freely.
On the surface, water molecules bind more strongly forming a skin. The sticks are attached to this skin, so we can order them easily. When you drop the soap, the skin of the water melts and the chopsticks float freely.
