Step 1: Choppy Choppy!
What you'll need:
1. The ugly soap.
2. A styrofoam cup, or other microwave safe container you'd like.
3. A microwave.
4. Knife or the likes.
5. Disposable cutting surface, Paperplate!
Collect all of your little pieces of soap. These are usually the ones that have become small, balled up, dirty, or disfugured from too much use. Don't get me wrong, hand washing is a good thing. :)
Gather all of the mutant soaps and put them on a paperplate. Get your knife (I just used a butterknife) and cut all of the soap into tiny pieces. The smaller the better usually.
