A slight exaggeration, but he worked on the mass spectrography unit at UT Dallas, and that was part of the Phoenix mission.
If you'd like to point out that it ended up having some problems due to an electrical short circuit and have a giggle, please do so now. :)
He also ended up clearing out the entire building one day, because I think he left some chemicals on a hot plate. Every time after that, when the fire department would get called for whatever reason, if the fire chief saw him wandering around, he'd bellow, "STEIN, WHAT DID YOU DO THIS TIME!"
