On the last day of the Ph1a lecture, a group of mole frosh decided to liven the class up with a prank. Having got permission from the Prof to interrupt class, they worked to install a Vanishing Cabinet (from Harry Potter) in the lecture hall.
When the lecture rolled around, there was indeed a Vanishing Cabinet there. But that was merely the beginning…
Near the start of the lecture, a student walked out and proceeded to sit down and take notes.
But then some Death Eaters showed up, escorting the student out.
A little bit later, some more students entered the room, looking for the Death Eaters.
And near the end of lecture, a Hogwarts professor showed up to give the Prof a letter.
It was good fun all around, and definitely livened up the last lecture.
