Lab BS

So I have to do a straight up experiment from scratch, so we can analyze the data for one of my classes, but the lab staff has been pretty uncooperative, poking holes into stuff that doesn't make sense and stuff of the sort.

At first I thought they were being oddly aggressive, and then I found out someone'd just broken some lab equipment totaling over 30 grand... Suddenly it all makes sense.

But I gotta say -- surely, and I mean, SURELY, modern centrifuges have to have some kinda failsafe in case you don't load in the counterweights, right????
