OK... their understanding of the basic propeties of physics are off a bit - just to try to fool the ignorant masses.
Ice floats, even polar ice caps float.
When floating ice melts, it does not change the water level.
Put a block of ice in a glass of water and watch it.
It is called "displacement"... use the brain God gave you... look it up.
