Did you dream of being Ariel from the "Little Mermaid" when you were a child? While there are no real mermaids in the world, make a realistic latex mermaid tail as fancy dress or theatre costume. Latex is a soft, rubbery material that is easily moulded. Mould the latex directly on your legs to make a realistic and comfortable latex mermaid tail. Relive your dream and make your child's wish come true.

  1. 1

    Use a utility knife to cut the frame of the mould out of styrofoam. Cut two styrofoam sheets 1.2 m by 90 cm (4 feet by 3 feet) for the front and back; cut four styrofoam sheets 1.2 m by 15 cm (4 feet by 6 inches) for the sides; and cut two styrofoam sheets 90 cm by 15 cm (3 feet by 6 inches) for the bottom. You will make 2 halves of the box.

  2. 2

    Place the front piece flat on the ground. Pour superglue on the edges of the front piece. Stand two side pieces and a bottom piece on the edges of the front piece. It makes a three-sided styrofoam box. Let the superglue dry for five minutes.

  3. 3

    Pour plaster into the inside of the styrofoam box. Mould the plaster to the shape of the front half of a mermaid tail. Shape the plaster into an hour glass shape. The bottom of the hour glass is the tail. The top of the hour glass fits around your waist. Dry the plaster for 10 hours. That makes the front half of the tail. Repeat Step 2 and 3 to make the back half of the tail.

  4. 4

    Rub petroleum jelly on the surface of the plaster on the front and back box. The petroleum jelly lubricates the mould to easily remove the latex in the future.

  5. 5

    Face openings of the styrofoam boxes toward each other. Place duct tape to connect edges of the front and back boxes.

  6. 6

    Wrap cling film around your legs up to your waist. Cover the cling film with petroleum jelly. Sit with your feet straight and together. Spread plaster around the outside of both of your legs from waist to your toes. Dry the plaster for 3 hours. Remove your legs. Let the plaster harden for additional 7 hours.

  7. 7

    Place the plaster mould of your legs into the middle of the styrofoam box. Pour latex inside the styrofoam box, but outside of the plaster mould of your legs. Let the latex dry for 10 hours. Remove the styrofoam boxes and plaster moulds from the outside of the latex. Remove the plaster leg moulds from the inside of the latex.

  8. 8

    Place your legs into the latex. You are ready to wear your latex mermaid tail.
