1.Adding soap lowers the water's surface tension so the drop becomes weaker and breaks apart sooner. Making water molecules stick together less is what helps soaps clean dishes and clothes more easily.
2.Using the presented protocol, the surface tension was measured by probing the bending curvature of soap films made from different conditions. Our measurements show that a soap film has a surface tension of 30 mN/m if its thickness is relatively thick or if it is made of soap solutions of higher concentrations.
