As a retired teacher of 71+ years, one skill one develops is reading many types of writing..and in that, you are often doing this while facing the student, reading it upside down
A mimeograph machine is a duplicating machine that works by forcing ink through a stencil onto paper.This doesn’t have a strong odor. A ditto machine is also called a “spirit duplicator”. This refers to the methanol ,a major component of the solvents used to disolve the “inks” on the ditto masters in these machines. The alcohol is the smell people remember.
I realize this is a cartoon and not an online astronomy class….but I see these zooming comets mentioned in comics and in movies…for those who have never seen a comet…hear is a FYI..“Comets are going really fast. However they are also really far away. This means that from our viewpoint on Earth, it will just change its position in the sky over several weeks. So, there isn’t that ONE TIME you will be able to see it. It should be visible in the sky for weeks.”
