After his amazing jump Harry couldn't stop thinking that maybe he could convince people that he could fly. So he thought he would go medieval and try using a broom. His plan was to jump off a swing so far that it looked like he was flying. While he was in the air he would put himself on a broom, then he would land gracefully – basically he would make it look like he was landing from flying – not landing from jumping. He practiced everyday with help from Dudley. Dudley would toss Harry the broom when Harry told him he was ready to jump. By the time summer vacation was over Harry thought he was ready to test it out on his classmates at school.
"Dudley could you hand me the broom now?" Harry asked. He was swinging so high he was almost level with the bar. As Harry came back the other direction he grabbed the broom from Dudley. Then he jumped on his way back up. It was a beautiful jump – perfectly executed. He pulled himself onto the broom at just the right moment, and there happened to be a lot of students looking his way that exact moment. They saw him appear to be flying, and then land as if nothing big had just happened. The students were all amazed. They all knew his reputation for pranks, but they could not figure out how he had done it. They told everyone they knew about the boy who had flown on their playground.
This story created quite a stir and the wizarding world got wind of the story. They decided they should check it out. They went to the school where it had been rumored to have taken place, and they began questioning students about what had happened. They all said it was Dudley's cousin. Now Harry had been kept inside during that recess, because he didn't do his homework – being so focused on his prank. They could not find Harry, so they decided to find his cousin. They could tell right away that Dudley was a muggle, so they weren't quite sure what to make of it. Dudley explained how Harry and Dudley had been planning this prank together most of the summer. Once they realized it was a prank they spread the world to the muggle news about the great and elaborate prank played by the nine year olds. After that they forgot about the incident entirely.
