In Science today we learned that plain water has more cohesion than soapy water. Cohesion is when similar molecules stick together. Soap reduces the amount of cohesion in water.
In this experiment we filled plastic cups with plain water and soapy water. We wanted to find out which liquid heaped higher over the brim of the cup. Plain water heaped higher because it has more cohesion.
