Have you ever thought to test a drifter buoy? Well you probably haven't. Ms. O'Brien's class had to put some deep thought in to were to test ours. We are going to test in the Hudson River. Mr. Tanenbaum is going to go in a kayak and placing the buoy in the water to see if it works. We figured that if we put the buoy in the Hudson River it would be a good place because it is local and we could go on a field trip there.
