Work for a geotechnical engineering company. I am a lab rat, get to crush concrete cylinders in a hydraulic press to determine their pressure rating to ensure that house foundations and the like can hold up to the forces imposed on them. I also do some moisture testing.
Best part of my job is I get to drive around a 2000 f150 (not good) and pick up said cylinders all over the greater sacramento area. It even has A/C!!!
