layer

Hi everyone, I would like to make a gobstopper soap, meaning a soap that’s round and has many layers just like a gobstopper. How do I make this happen? Every feedback is appreciated as this is quite important to me! (Its for a school project)

I have been using CPOP lately and am having trouble. Every single batch is giving me a thin sticky white bubbly layer on top. I thought it might be soap ash or lye film but I can't find anyone who is describing this a sticky, just a powder and mine is not a power. Help?? What can I do to...
