My experiment by Huffjackie

My materials included 5 books. I used the Diary of a Wimpy Kid and 1 39 clues. A metal spoon and a rubber ball (meidum sized). The purpose of the experiment was to see if I could toss the ball up in the air and if it landed on the books, roll straight. I did my experiment 20 times and the ball rolled straight once out of the 20 times. The other times it rolled over to the left or right. I deemed my experiment a failure in that it did not go straight enough times, but it was a success because it annoyed my mom. :)
