Here’s a beautiful video detailing designers Marc Newson’s process for making an hourglass. A huge cylinder of glass is placed on what appears to be a special lathe, and is then spun while heating to create an hourglass shape. Next, metal beads are added through a hole in the top until they take the appropriate amount of time to fall through the timepiece. Finally, the hole is sealed and the hourglass is ready for use.

I love this video. This kind of project videos are mesmerising. I remember a similar video, “fabrication d’une lampe triode” (Here’s a link http://www.dailymotion.com/video/x3wrzo_fabrication-d-une-lampe-triode_tech)
The hourglass is an amazing art form, but that video is an art form all its own.
