Homemade Rainbow Cake

I love making cake and recently I was assigned a Science project. For this project my teacher said that an Arched Rainbow Cake hadn't been made so I figured this would be my project because I love challenges and I love baking.

In this recipe I used a round 9x9 cake pan not an angel food pan.
