Today's lesson: Airlocking a Sharpie is a bad idea.
We have needed a new marker in the glovebox for a while, as the one we have now only writes when held at a really awkward angle, leading to a lot of illegibly labelled samples. Today we had an extensive discussion about the best way to bring the marker in, balancing the need to keep it from bringing in moisture against the need to not dry the thing out. We discussed whether we should cycle it in overnight or just the way we do for regular things. Cap on or off.
At no point did it occur to any of us that it might not be such a great idea to put it under vacuum.
So yeah, that exploded. Next time, we blow it in. :p
