How do i make floating plastic worms for fishing?

[bassnatcher77]

I love fishing plastic/rubber worms, especialy floating topwater ones. I recently moved and lost access to my favorite brand, so i thought i would make them myself. I know you do the melting, and the molds.......but i need to know what media is used, how you mix colors, and all the good stuff. If anyone is in this business and would like to throw me some pointers i would appreciate the help, thanks. Mainly what tools and what materials and where to find them.
