Chemistry

Brad and Carol were marine scientists with a problem. They wanted to discover which color sharks would attack. Brad believed that sharks would attack dark colors, such as black; but Carol believed that sharks attack bright colors, such as yellow. Brad wrapped one float with a black life jacket. He placed it in the water and observed the behavior of the sharks. After two hours the float was taken out of the water undisturbed. Brad and Carol then placed a yellow jacket around another float and placed it in the water with the sharks. In the two hours, this float was attacked four times. Brad felt that this problem needed to be studied more. He then took two life-size dummies and put a yellow life jacket on one and a black life jacket on the other. Both dummies were then put in the water. Two hours went by and sharks did not attack the dummy in the black jacket, but they did attack the dummy in the yellow jacket six times.
