That bubble of air at the top is for expansion, not flotation. Or not JUST flotation. Given that gas stations have their tanks underground where it's generally colder than the air, it would damage and eventually burst the can with repeated summertime use. Fluids to NOT compress. At all. Air (or gasoline fumes in this case) do.
ReplyDeleteYou don't need an air bubble for floatation. Gas is significantly lighter than water and if contained will float just fine on its own.
