Curious George toured Yps around the ArcelorMittal Differdange steel plant, Luxembourg. The hot bar in the background is positioned to be flattened by rolls. It is really hot there, even several meters away; and very noisy.

 

Yps and George wanted to try out the controls and make their own steel products but they weren't allowed. The control tower looks exactly like a ship's bridge (way bigger than the corner in which the picture was taken).
