I was already having enough of this, so I just ignored him and began doing the experiment. Maybe I should've gone by myself after all. I set up the bunsen burner, plugged it into the gas outlet and weighed the crucible and magnesium on the scale. After basically setting up the entire thing by myself, Derrick finally decided to come back over, claiming that an image justified that what he had were tongs. It was simply incorrect. What he was holding was obviously tweezers, and he had scrolled down quite a significant amount before locating that image. Common sense would've shown that those tiny tweezers were obviously not meant for this experiment.
