At Mercury, the Ohio Players enjoyed their greatest success; not only did their sound coalesce, but they became notorious for their sexually provocative LP covers, a tradition begun during their Westbound tenure.
Objects float when the volume of water they displace is less than the volume of the objects themselves. When objects sink, the volume of water they displace is greater than the volume of the object. The principle may seem relatively simple: Light objects float and heavy objects sink.
The object is said to be buoyant when it floats due to low density. By spreading out the concrete used to make the boat over a larger volume, the apparent density of the boat becomes less than that of water. Hence the boat floats! Time: 90 min. (1 class period for making the barges and 1 class period for testing)
