Sherbet Surprise Bath Fizzies

Love bath fizzies? Do you think that you cannot make bath fizzies any more special?  Here is a recipe from The Soap Queen called Sherbet Surprise Bath Fizzies that has a special surprise in the middle.  Would you believe that this recipe was a guest post by Holly Port who wrote the book, Make it Fizz: A Guide to Making Bathtub Treats. I have this book and I have not tried any of the recipes but I am planning to try some really soon.
