When water was dropped onto the wax paper, the drops beaded. When we picked up the strip of wax paper and tilted it, the water drops easily slid around and combined with the other drops.
Water Dipped with Soap
As you can see in the video, the drop of soap broke the surface tension of the water drop on the wax paper.
Paper Clip on Water

If we were able to keep the paper clip on the surface long enough to add a drop of soap to the water then we would have seen the paper clip fall to the bottom of the beaker because the surface tension would have been broken.
Polarity of Water
Salt is a polar substance.
Oil is a non-polar substance. As you can see, even when mixed, the oil does not dissolve into the water, making it a water dreading substance as welll
Examples of Cohesion and Adhesion
Whether you notice it or not, examples of cohesion and adhesion pop up all the time in our every day lives.
