Demolition beast

Went back past the demolition site of the former McEwan's brewery. I'm really, really fascinated by these machines in action, they look like dinosaurs, crocodiles, very much alive really. This one was demolishing a wall, water was sprayed on the wall to reduce dust and at some point this machine reared its head above the wall and some water dripped out of its 'mouth' and it just looked like saliva dripping.

Scary and fascinating at the same time - I could watch on for ages.
