Helium _is_ absorbed into the bloodstream under high enough partial
pressure and does release bubbles when the pressure is released
too quickly. Heliox (Helium + O2) and Trimix (Helium + N + O2) are
common gasses used in the technical diving community, and they both
require decompression stops on the way back to the surface.

A strange and juvenile thought popped into my head, while reading about
dissolved He, and thinking about the decompression effects one experiences
while ascending in an unpressurized small plane.

We all know that farts are unavoidable as we get high in a small plane.
Those are the garden variety stinky ones, from breathing regular air. What
happens when you come up from the depths after breathing some He? Do you
fart Helium? g

I know, thirty lashes with a wet noodle! ;-)
