DOL-Fin Lets You Swim Like A Dolphin

We humans are strange species; we like to do what other animals are capable of, we want to fly and we want to swim. Why is that? It is because these acts somehow encompass the idea of freedom for us. Putting the philosophy on hold, an Aerospace engineer Ron Smith has come up with an invention that will allow you to swim like a dolphin and it is known as DOL-Fin and makes use of a rigid, wide hydrofoil-kind fin.
