It is a matter of density. For some equal volume of water and kick board, say the size of your fist, the kick board has less mass in that given volume than water does. This means that for the same volume of kick board and water, the kick board weighs less than the water within the Earth's gravity. Hence, the kick board has a lower density [density = mass / volume] and thus floats on top of water.
It is the same reason the kick board does not float in the air, the air has a lower density than the kick board! So what must be true of the Helium gas used to fill flying balloons and the air around the balloon?
Hope this helps 8^D
What else can I help you with?
Do fish always float to the top when they die or can they stay at the bottom?

How is mobile phone gold extracted?
The old circuit boards are simply melted in a furnace. The gold and other metals sink, while the plastics and other products float to the top as 'slag'.
Why do you not stack boards on top of each other when taking computers apart?
do not stack boards on top of each other because you can accidentally dislodge a chip on the boards or they can fall and break. always set them on a flat stable surface away from being able to be bumped and preferably in an anti static bag or on an anti static mat.
How do you tell which liquid will float on top of the other?
This is found out by knowing the densities of the liquids in question. The liquid with the smaller density will always be on top, while the liquid with the higher density will be at the bottom.
Will vinegar float in oil?
No. Oil will float on vinegar as vinegar has the same density as water.
Where does crustal plates float?
the plates float on top of the upper mantle
When water and decane are mixed which layer will float on top?
Water is denser than decane, so the water layer will sink to the bottom while the decane layer will float on top.
What is a shoelace kick in soccer?
when you kick the ball on the top of your foot between your toes and ankle, on top of your shoe laces
Why does seaweed float?
Seaweed has a part called a Float. This is often at the very top of the plant. The float mostly floats on the top of the water. The Float helps to keep the Seaweed buoyant. Seaweed floats because of the Float.
Does plastic sink or float in oil?
Plastic is less dense than oil, so it generally floats on top of oil. This is because oil is more dense than plastic.
If an object has the same density as the fluid it is submerged in the object will always?
Will always float with the top surface level with the water
