He/She constructs experimental apparatus using scrap metal, some custom glassware from the chemistry department glass blowing shop, an expensive sensor robbed off of last year's project, a chunk of stainless steel turned on a lathe by his/her own hands, some computer software, a little liquid nitrogen, and of course duct tape. He/She writes another paper.

My entry into astrophysics was observing far infrared using stratospheric balloons. While the gondola had a nice rigid core structure, anything that didn't need rigidity we attached to the structure with white duct tape (the usual grey kind tends to melt in sunlight when there's not enough air around to carry off the heat). After that project, I moved on to shorter wavelengths, but some of the other folks stayed with IR. 10 years and three generations of telescope later, they launched IRAS (http://en.wikipedia.org/wiki/IRAS). There wasn't any duct tape in that...
