A 10mm bubble has a volume of 523.6mm^3, and a surface area of 314.15 
mm^2 - a volume to surface area ratio of 1.667. A 5mm bubble has a 
volume of 65.45mm^3 and a surface area of 78.54mm^2 - a volume to 
surface area ratio of 0.833. So, in other words, as the bubble gets 
smaller each cubic millimeter of gas is exposed to a greater surface 
area of water.
