[net.physics] Ice in water + air bubbles.

BIESEL@RUTGERS (04/08/83)

	Forget the air bubbles: unless their density differs appreciably
from that of the ambient air, Archimedes's law still holds. Example:
imagine an ice balloon; it, too, will displace its own weight of water,
and when it melts, the level of water will be the same. 
	Second order effect: since ice has a lower density than water, 
a given quantity of ice will displace more air than the same amount of
water. Consequence: very large chunks of ice melting should raise the level
of the water slightly.
