A few weeks ago, #RotoloClass students were sorted into the four houses of Hogwarts: Gryffindor, Slytherin, Ravenclaw and Hufflepuff. (Students who were absent for the Sorting Ceremony were formed into a fifth group: Muggles.)

Each house of aspiring wizards was challenged to use their best magic to create a video with the best shot of “going viral” online.

The Assignment was simple: There are no rules on content. It could be comedic, informative, a display of talent or anything else the house decides has viral potential. The only rule was to do nothing that is against the law or unethical in the process.

What follows are the submissions from each house, as well as the muggles. These videos were viewed in class on November 17 during the “Quidditch Cup of Viral Videos,” but they need your help to be truly viral. A winning house will be announced next week and your votes can help determine who takes home the prize.

To vote, choose your favorite video below and tweet your choice using the #RotoloClass hashtag. Be sure to include either #Gryffindor, #Slytherin, #Ravenclaw, #HufflePuff or #Muggles in your tweet so we count your vote accurately.
