Science -- Your Future, Scotland's Future
Mark's Steam Engine
The result of many hours of work, this engine was built entirely from scratch, every part being fashioned from the scrap metal pieces Mark "found" in the University skips...

Eventually it'll be part of a moving* exhibit, showing you how the internal mechanism of such a machine works.

(Note: if the GIF image above isn't rotating, check to see if your pop-up blocker is suppressing animations.)

* That's 'moving' as in 'animated', rather than being particularly poignant, though of course it may be that as well...
