The potential problem...

As our music video is on a rooftop we have to dissemble and transport the drum kit from the music room in our school to the rooftop that we are using. The door that leads onto the roof is relatively small and we were worried that the largest drum, that makes up part of the drum kit, wouldn't fit through the door so we decided to measure it to make sure that it would fit OK. The pictures of our group members measuring both the drum and the door are embedded below:

Fortunately, we discovered that the door was large enough to fit the drum through it.
