Last week in Biology we learned why water molecules are "sticky." In the first lab Tanner 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 of the penny, we were able to drop 46 droplets when the record was 65 droplets. 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 26 droplets. 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. We had to wet the string before trying to send the water down the string. We were not successful in getting it all the way down the string but we got pretty close.
