Well I got around to making the 7-up type soap this weekend. Didn't come out exactly like I had planned because I guess I didn't wait long enough to pour the second layer. I ended up with the layers blending together, but I must say I was very pleased with how that ended up looking. Had to do a back lighting photo to show how cool it looks.
The bubbles on top are pretty cool, but they are on the fragile side so maybe it was for the better my other bubble layer ended up being blended in.
