I hope this is what you are looking for. Found it at http://www.soapmakersupplies.com/soapmaking/SoapRecipes_Home.html#Foaming Soap in a Bag Ingredients: Clear polypropylene bags Curling ribbon Translucent soap base Fragrance Oil or Essential Oil (Choose type and amount you like) Rubber or plastic fish, duck, alligator, etc. Instructions: Open and stand bag upright in a cup or bowl. Melt the soap in the microwave, making sure it doesn't boil. Add fragrance once soap is melted. Pour a small amount of soap in the bottom of the bag. Place the plastic fish (or other animal) inside the plastic bag on top of the soap, so that it stands upright. Cover the fish with more melted soap. If using two fish, allow soap to form a film that will hold the weight of the fish. Place second fish in bag and cover with soap. When soap is cool, gather bag at top and tie with curing ribbon.
