Earlier this week, construction workers poured concrete for fourteen consecutive hours at the future site of a fountain and entrance to one of the World Trade Center towers. The Port Authority released a time-lapse video of the process, which we enjoy not only because it's fun watching people move around at light speed, but because it does make you appreciate all the effort and activity that goes into just a single day of work on the project. Especially if, like all the Intel editors, you have no idea how people are even capable of figuring out how to build a structure like this from scratch. [Port Authority]
