This Model of Stephenson’s Steam Engine was made in 2008 by master glassblower Michal Zahradník.

One nit: at about 1:40 it says to notice the steam exhaust — steam is water vapor and is invisible, so you can’t notice it. That’s one reason that steam line ruptures are so dangerous. If you can see it then the water has begun to condense; what you can see are small water droplets.
