Effective prosthetics for your YouTube videos

Step 4 Other bulking materials.

I wanted a tail, so I used foam rubber pipe lagging which is very cheap, reasonably pliable, but stiff enough to carve and shape. I cut the pipe lagging into sections then carved and Dremel sanded them roughly to shape. I added some 'vertebra' looking bits and glued the sections together using a tongue of sponge and regular general purpose glue.

After two days work I had a four foot long tail. That's yours truly in the image.
The tail next needs 6 coats of liquid latex which will seal it and make it incredibly strong.
