Those guys are dropping that bottle 200 feet from where they started.
They are not trying to go anywhere with it, and in fact, genius, they
are able to do so because they are riding an extremely powerful scooter
which will over come the additional drag. 

Those pictures are not of me, I wear them on my hip and one on the left
side, nothing on the right.

I might add that you are not qualified to even discuss this. I also
might add that these guys can carry six or more bottles, and that JJ and
I did a seven bottle dive with no problem. You try that and get back to
me with how stupid I am.
