NASA engineer Rockergirl Nettie Roozeboom checks out a generic launch vehicle model covered with pressure-sensitive paint that shines when exposed to blue light. The test article is seen mounted in a wind tunnel at NASA's Ames Research Center in California.

Its intensity varies with pressure so NASA engineers can visually see the how structures perform in their wind tunnels. Far out, man!
