Rube Goldberg (Goal 1- Open a Book)

Okayy, I decided to call all my contraptions from now on Rube Goldberg's.
This is my first Rube Goldberg machine that actually does a goal now. Oh yes, I also thought that the marble boards that bestpal and FunnyBoi69 used were cool, so I decided to create my own (lol I had to use a DVD player box as cardboard because I had no other pieces of cardboard that were big).
