Great summer cleaning of 2015
The Great Summer Cleaning of 2015 was conducted, as the name implies, in the summer of 2015 by the COSInauts who were around for the summer including:
This cleaning involved fully removing all furnishings from the COSI lab one side at a time, shampooing the carpet, and reassembling everything after removing gum, dusting all the computers, and generally cleaning every item in the lab.
It was a lot of work, but it is the opinion of those involved that this is something that should ideally be done every few years. It makes the lab *feel* much cleaner.
