I work at COSI in Columbus, and we have a computer that can run video real slow. On this computer we have a clip of the space shuttle taking off. Right before the space shuttle engines light up, a cloud rises from the launch pad. I have heard two conflicting explanations: that the cloud is steam from water; or that the cloud is from liquid nitrogen. Both had in common the idea that the cloud is the product of some coolant of some kind. What is it really?
