I wonder how well you would have to be able to swim to overcome the density/buoyancy difference if swimming in a pool of gasoline?

It depends how long you can hold your breath. I imagine many people would be overwhelmed by the fumes before they got very far.

It's a pretty drastic density difference. I think an Olympic swimmer would have a hard time staying above the surface.

Ah, 12 hours later I log back in to see skimmers got autocorrected to swimmers.

Gasoline fight!
