Share a little about the materials, processes, and techniques used to create this cake Fondant, buttercream, gelatin, balloons What are you most proud of? The bubbles. I've never tried this technique before. They didn't come out perfectly, but they were good enough and I learned a lot. What advice would you give someone starting this project? Give yourself several days to let the bubbles dry, make lots of extras, and buy more gelatin than you think you'll need. Be very careful about how to prop up the bubbles to dry. I had some that got stuck together or damaged because they were touching the styrofoam block that was supporting them.
