Actively Supported Tower (part 1) (Patreon)

This video was going to be made public Tuesday morning (6-26-17) but while I was filming this veritasium uploaded a similar video. that was not planned and the videos are clearly unrelated but as the internet goes uploading a "copycat" video twice in a row would ruin me. so I think I'll hold this video as unlisted for a while. perhaps I'll start work on the other 2 videos and publish them in rapid succession in a couple months from now.
