Yes it does. They are made out of foam. Foam floats very well because it is little pockets of air.
A supine float is floating in the water on your back with head above water.
A cork has a low density. It is lower then water. That causes it to float.
Because it is denser than you
You float face down in the water. You only move to get air.
Because it has air in it. Air weighs less than water therefore air floats.
by swimming and walking and running, and they can float on water
By Its Buoyance.
The density of sea water is greater the fresh water. The more greater density the larger is its upward thrust.
It is easier to float because the sea water is denser than water found in a swimming pool. This is caused by the salt in the oceans.
The salinitiy of the water allows you to be more buoyant.
newtest3 Any object will float better in salt water. It is denser, and pushes the object, (an egg in this case) To the surface of the water. Have you ever tried to float in the swimming pool? In the ocean? Well the ocean is much easier for this reason. Next time you go swimming, try to be the egg!Remember... Oogla knows all!
Sea water is easier to float in, but wave make it harder to swim in.
