reddit seems to think there is a vacuum at the top of the tank

It seems to be the same principle as a bathysphere. So maybe not a vacuum as such, but a way to level off the pressures

Itâs not a vacuum, but it is lower than atmospheric at the top, due to hydrostatic pressure. You can calculate the pressures (approximately) just by looking at the tank. Assume the tank is 48" tall. At the opening in front, itâs atmospheric pressure = 406 inches H20. At the top itâs about (atmospheric - 28 inches H20). At the bottom about (atmospheric + 20 inches H20).
Below is a chart converting inches H20 to other units. Calculations are left to the industrious student.

Speaking of âpuzzling evidenceâ, I just got notification that there was one new post in this thread, but in fact I hadnât been getting notifications for it since around post 15 or so.

I just noticed that someone has posted a periodic table to the officeâs kitchenette corkboard. Not a joke one or a software developer one, just the regular kind.
The most applied chemistry we do around here is dissolving spoonfuls of sugar into cups of coffee.

Thank you for this. 
Itâs like the proverbial two great things that taste great together, and that I never would have imagined had actually been combined.
Sting was one of my earliest musical enthusiasms. Zappa, I came to much later in life, and Iâm no expert on his oeuvre, but I think he might legitimately have been some sort of genius. I had no idea theyâd ever crossed paths.
