On Earth, the pen floats in water, but doesn't float in air.

This is surely also true on the moon? The relative densities of the pen and the fluid you put it in don't change depending on the gravitational field they're in.

Hmm. I actually don't know the relationship between gravity and buoyancy -- a moment with Google and I'd know, but in the meantime I'm in the position of relating to all those people who answered incorrectly.
