In the fall of 2016 my class all had to create design challenges, and mine was chosen. I did mine about Harry Potter. I participated in judging and creation of the t-shirts that the judges wore.
In the Wizarding world of Harry Potter, Muggles (or non-magic folk) have always been shielded from the sports of the witches and wizards. In the old days, there were laws that witches and wizards could not play quidditch unless they were 50km away from muggle cities, and even then they had to cast a spell to keep muggles away. Times have been changing, and people have become more accepting to magic (except for the Dursleys). Muggles have been playing Quidditch for a long while, but not on flying brooms. We now have the technology to shoot Quaffles (the scoring balls) into the three hooped goal posts of different heights.
