Vincent you are right.... gravity alone would not create the power to form a vortice. However as explained in the next thread, probably vacuum created will give the impetus required to form the shape. However the question remains, why this type of shape, why not something simpler? Doesnt nature believe in simplifying itself???

Surface tension is the reason, this is the reversed culmination of momentum. |
