P2_6 Out with a Bang

Abstract

In the Harry Potter book and film series, Wizards are able to disappear at one location and reappear at another instantly. This instant disappearance creates a sound which we found to be 160 dB, approximately that of a plane taking off, and significantly louder than the described ‘pop’ or ‘crack’ sound in the books. We also calculated that, if the method by which this occurred was due to the Wizard travelling at the speed of light, they could transform their body weight into 94 EJ of energy, enough to power the United States for 24 days.
