Big Red Button

I think it's human nature to be fascinated by the "Big Red Button." What does it do? Why is it there? Is anybody looking, could I push it?

This summer, as I've mentioned in earlier posts, I'm doing an internship at ODOT. Yesterday I went on a tour of their lab, looking at how they analyze soil, rocks, pavement, and all that exciting stuff. While wandering the rock room we walked by a machine that had a big red button. The fact that it had a big red button was cool in itself, but what the button was labeled made it blogworthy.



Yep, it's an Emo Button. So, your task is to tell me, in the comments, what does a big red Emo button do? Most creative gets a cookie (seriously, I'll mail you a cookie)
