Some pictures and clips from the second (and last) time I wore my tail.
I already got a fan ;)
The tail gave me a lot of drag and was heavy to swim in. Lots of fluke, not so much propulsion. (I want to be perfect the first time I do something, it's dumb, I know)

When I turn at 01:00 you can see that the fluke bends very, very wrong.
