An actual lab: "Carolyn Pearce uses a piece of equipment at the Lawrence Berkeley National Laboratory to study mineral samples from a nuclear reprocessing site. The data collected will be used for a better understanding of nuclear waste. Jessica Brandi Lifland for USA Today."
Movie lab: Hard to criticize this movie. Note the safety goggles (and how they're being ignored), the outdated-for-the-time equipment, and that Mitch is totally obsessed with data readouts.
Racks of equipment, dingy lighting, looks like little is happening yet the students look like their lives hang in the balance. Yep, a lab.
Okay, the toque blanche and the smiles might be deceptive, but still a lab. (I encourage the reader to look up this clip for a pretty good joke, though.)
