We’ve been having a bit of a tech-crush here at MAKE, on pneumatic tube systems. We wrote about it in a recent Lost Knowledge column, talked about it on Make: Talk, and Dale went to Molly Wright Steenson’s inspiring talk at ETech. In this San Jose Ignite video, entitled “It Really is a Series of Tubes,” Molly presents a wonderful survey of pneumatic technologies of the 1800s, all in five minutes.

Now I’m REALLY in love.
