Waiting on the World to Change

For all you that love the history of the earth, I have a project due at the end of the semester and I need your help. I have to make a geological time scale but I have to be creative. Breaking it down, I have to make something that is in layers. I was thinking of a jar with layers of different color candy. Just something that represents each time period of the earth. I hope that makes sense. Below is what a time scale looks like on paper. Now I have to make it a project.
