Things You'll Need
Rapid-setting gypsum cement
Mold release agent
Someone to model
Slip on a fake nose and the transformation can be dramatic. You can become a boxer with a flat, squashed hooter or turn up your snout to resemble a pig. If Halloween is coming up, you could also add some warts and a pointy end to your fake beak and become a cackling witch. Whether it's to dress someone up for a costume party or to make up part of a costume for a theatrical production, creating a fake nose isn't as hard as it sounds.
Remove any makeup from your model.
Apply 1/4 pound of prosthetic alginate to the face within a 2-inch radius of the nose and on the nose itself.
Cover all of the prosthetic alginate with plaster bandages once the alginate becomes firm.
Instruct the model to lean forward and gently release the mold. Be patient and the mold will come off intact.
Add extra plaster bandages to turn the mold into more of a bowl shape.
Place the mold in a box. Pour gypsum cement into the mold until it is full. You want the cement to be flat and smooth.
Remove the gypsum cement from the mold once it hardens.
Add extra features to the nose with oil-based clay if desired. For example, you may want to extend the nose and add warts if you are making a witch costume for Halloween.
Use a paintbrush to apply mold release agent to the sculpture.
Cut the bottom out of a container, like a yogurt pot. It must fit the entire nose inside without squashing it. Place this over the nose. Cut away most of the excess from the sculpture.
Fill in any gaps between the nose sculpture and the base of the container with clay. Wrap a rubber band round the top of the pot and the base of the sculpture.
Fill the container with gypsum cement and flatten out the top.
Take out the gypsum cement once it hardens. Clean the inside of the mold.
Pour liquid latex into the mold and move the mold so the latex gets reaches everywhere. Drain out the excess latex.
Leave this to dry overnight. Push your thumbnail into the latex; it is ready once doing this doesn't make a dent.
Apply a little talcum powder to the latex and gently pull it out.
