Industrial keyboard
I worked for a time on QA of IBM's "Industrial" PC, intended for use in places like factory floors rather than offices. One test put the system in an excessively smoky and dirty environment - after a while the keys on the keyboard could not even be depressed as there was so much gunk caught underneath the keycaps. But we were able to simply turn it over, shake and tap it, and everything started working fine again.
