Waterbird allows to walk on the sea!

A friend mailed me today a demonstration video for the waterbird mashine. You step on it and do a permanent bend/rise movement. And...you can walk on the sea! I should be a great feeling.
I will search where I can buy this mashine. Lots of fun but would be pretty dangerous in Bosphorus.
It would be a better idea to use it in summer resorts like Çeşme or Bodrum.
The device is also perfect for fitness. Fun and sports combined. Very cool!
