Sticky Water
Surface Tension is a pretty difficult topic to understand but it is definately a very interesting one. Today I found a great website that explains the phenomenon known as hydrogen bonding. Hydrogen Bonding is the attraction between a hydrogen atom and a oxygen atom that causes water to be "sticky." You can click on the link or wait till our fascinating presentation to find out how hydrogen bonding works and how that relates to surface tension. http://www.exploratorium.edu/ronh/bubbles/sticky_water.html. It is amazing how bugs like the water strider can walk on water because of the strong surface tension of water. That has more to do with physics than chemistry but it just is interesting that because of a low center of gravity and stable positioning it can walk on water.
