New Zealander Nadya Vessey lost both of her legs to the knee when she was a child. About two years ago, she approached Weta Workshop, a company that specialises in costume design and special effects and asked if they were interested in making her a prosthetic mermaid tail. Vessey says the idea came to her when a little boy asked her what was wrong with her. She told him that she was a little mermaid and the idea stuck. They agreed to her request and recently completed the final product. The video shows Vessey being fitted with the tail, attached to a skin tight body suit, and adorned with mermaid make up to complete the illusion. Getting used to the prosthetic has been a lttle more difficult than creating a credible visual though: "A prosthetic is a prosthetic, and your body has to be comfortable with it. You have to mentally make it part of yourself," says Vessey.
