Does clay sink or float in water?
Since clay is more dense than water, a ball of clay sinks in water, no matter how big or small the ball of clay is. If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water.
Why does a clay ball sink but a clay boat float?
The clay has the same mass no matter what shape it is; however, the ball takes up a smaller space than the boat shape. When the clay ball is placed on the water, the ball pushes out less water than when the clay is in the boat shape. The boat shape floated because it pushed aside more water.
What is the best shape for a boat to float?
A flat bottom is best, with sides to keep out the water and a large surface area that touches the water. Boats with lots of surface area are very wide, with lots of space inside. When pennies are added, the boat will float if the combined density of the pennies and the boat is still less than that of the water.

What is the reason a coin sinks when put in a glass of water?
Light bends when it passes from one medium (water) into another medium of a different density (air). This bending of light, called refraction, causes the apparent position of the coin to change to a shallower position1 (see diagram). The light bends when it passes from water to air on top of the water.
What happens when you press the clay ball with your hands?

Why do heavy boats float?
The air that is inside a ship is much less dense than water. That’s what keeps it floating! As a ship is set in water, it pushes down and displaces an amount of water equal to its weight.
What shape of clay boat holds the most pennies before sinking?
Question: What shape boat can hold the most pennies? Hypothesis: The flat boat because its weight can be spread out.
Why do I sink instead of float?
Muscles are generally more dense than water and cause us to sink. Fat is less dense than water, party because it contains oil, which floats on water. Those of us with a higher fat to muscle ratio will tend to float. Yes that’s right, fat people float better than muscular people – generally speaking.
