Weta Workshop typically handles special effects for movies like The Lord of the Rings and Chronicles of Narnia, but that’s not the only work they do. After an encounter with a curious child, amputee Nadya Vessey contacted Weta about the possibility of a prosthetic mermaid tail. The studio was able to create a mermaid tail for Vessey, allowing her to swim through the water with ease. That’s right, this is no mere pool toy (though those are pretty awesome), but a fully functional prosthetic that allows Vessey to enjoy a dip in the ocean like no one else can… well, no one but mythical creatures that is. Check out the video (and be patient with the ad) below.
