I'm having kind of a cranky day, so the introduction of Inflatable Thorin gave me a much needed laugh.

how it's so often the guys who start the subversion (yes, looking at you Daniel, CG and NoWiz) and leave the girls to take the blame.
We're just wondering how dense Thorin is, with or without oiling.
Disclaimers: The words of noWizardme may stand on their heads! I'm often wrong about things, and its fun to be taught more....

Or "Hold off! unhand me, grey-beard loon!"

pressurizing the barrel would make it less buoyant. Pumping more air in adds to the mass without increasing the volume (at least, not significantly), therefore the overall density is higher and the barrel must float lower in the water. Even pressurized air is very light, so it would not be a big difference, but it would not increase the buoyancy unless the pressure was high enough to expand the volume of the barrel without splitting it open.

Getting back to the physics, pressurizing the air inside the barrel was probably done just to try to impress the ignorant spectators. Annie Taylor was a penniless 63 year old unemployed teacher when she went over the falls in a barrel, and she did it purely for the money. Since the drop only takes less than 4 seconds, there is no need to put more air in the barrel in the first place.
Don't mess with my favorite female elf.

Yes, Annie Taylor was a tragic story, in my mind.
It's interesting to look at what we perceive to be important variables vs. what really needs to happen to work. Seeing the reactions here sheds light not only on the real science but also on what filmmakers are up against in terms of audience perception. Your piece points out how things do work, but SPJ still has to balance that with what people will see as being plausible.
Still, reading the science behind the scene is a lot of fun! Thank you again for posting this piece. (I apologize if I shanghaied it with my silliness. Feel free to spam my piece when it comes up later this month!  )
