Last week in Biology we learned why water molecules are "sticky." In the first lab Nika, Serena, Katrina and I did, using a dropper and a penny, we placed as many drops of water on the penny as we could WITHOUT spilling off the side, we only got 29 when the record was something like 65. Then after cleaning the penny and droper we used the same tecquniques but instead of using water we used alcohol. With using the alcohol we only got 23 drops. We learned in this lab that water has buoyancy.
After realizing that water is very "sticky," we did a few tests. The main test was to see if we placed one side of a string to a beaker with water in it, and the other side to a beaker without. we raised the beaker with the water pouring the water on to the string to glide down to the empty beaker.
