The scientific name for water striders is Gerris remigis . Now you might think that skimmers have some sort of special feet or ability that allows them to do this trick, but it is actually the water that makes this type of travel possible. Chemically, water is the most important substance on the planet. We need it to drink and grow and develop. Without it, life on Earth would be impossible.
Water is also very simple.
Simply put, every water molecule is made up of 2 hydrogen atoms, and 1 oxygen atom. You see, hydrogen is a very weak electrically while oxygen is much stronger. When the atoms bind together, the oxygen shares electrons with the hydrogen. The result is that electrons in the molecule spend most of their time floating around the oxygen end of the water molecule, leaving the hydrogen end alone. This imbalance makes the water molecule act just like a mini magnet.
