Transforming Optimus Prime Birthday Cake
When I was a kid, I had a Transformers-themed birthday party, and I had a cake with a crudely drawn Optimus Prime on it made out of colored icing. Never in my wildest dreams did I think I would see an Optimus Prime cake that actually transformed, but that's exactly what this kid got for his sixth birthday! His dad, Russell Munroe, made him the custom birthday cake that transforms from Prime's truck form into the robot hero. You can watch the cake in action in the video below. I also included a video that shows us the mechanics of what lies under all that cake and frosting.
