Rainbow Spheres (M&P Soap) Tutorial

There one point in my life when I was growing up I was into clouds and rainbows.  I really got hooked on these because of the cloud wallpaper in the boy's room in the movie of Kramer vs Kramer.  When I saw the Rainbow Spheres Soap Tutorial on The Soap Queen's website, a flood of my youth came rushing back. Since rainbows bring smiles, why not create this colorful sphere soap.  It is an intermediate project that takes 90 minutes to make eight soaps.
