The Amazing Molecule

                      Water is only made up of three atoms that when bonded become one of the most important necessities of life. Our bodies are made up of about 70% water. It is a cohesive liquid which means that the molecules hold together using a hydrogen bond and stick to other water molecules. It also shows that water has a high surface tension. During our experiment we put drops of water on a penny. The water kept building up until the molecules couldn't fight gravity any longer. Another example of the hydrogen bond is when you start to boil water. When it starts to steam the water molecules are breaking off of each other with a lot a energy. Water is also adhesive with many things like string, paper, and tubulars of trees. As an experiment to explain this concept we took two beakers and filled one up with water and left the other empty. Our objective was to get the empty beaker full of water by having it travel along a string. We were able to a piece of wet string that was 16 feet 6 inches long. How we did it is we knew the water would bond together and travel down the string. This experiment showed both these properties of water. Water is a adhesive and cohesive molecule.
