Swimmer's hand paddle with positive buoyancy

[Category : - HEALTH- Fitness- Swimming]
[Viewed 182 times]

The hand paddle is made with positive buoyancy and has a hole.
The swimmer can handle the paddle by grabbing the inner surface of the hole. The outer surface of the hole will prevent the hand from losing the paddle. Then swimmer pushes the paddle deep into the water - this action creates the thrust and accumulates the swimmer's energy.
Then swimmer moves the paddle from the deep to the surface of the water - then the Archimedes power helps the swimmer create the thrust.
