When the buoyancy created by an object upon touching the water surface is less than the gravitation pulling it down, the object sinks. They sink until enough water has been moved to match the weight of steel and air in the hull. For example, the density of an object compared with the density of water will determine if the object will float or sink. Wow, who would have thought? 0000096303 00000 n 30 seconds.

When the object is very light. The contradiction to moving is staying still, to talking is keeping quiet, and inhaling is exhaling. Paper, kites, gas-filled balloons, hot air balloons, dust, birds, flies, airplanes, satellites, soap bubbles, feathers, dried leaves will all float in the air. This is because the solid form of water, ice, is less dense than the liquid itself. Another way to experiment with different densities is to take a pencil, a cork, a paperclip, oil, cotton ball, and stones and suspend them in water to find which predictions were correct about the densities being less than water.
