Please don't try any of this at home. Well not unless you have cliffs or a tin mine in your back garden.
The mines are disused, very difficult to access and rarely visited. I shouted down several times to make sure no one was below. Also, any passageway leading to the bottom of the shafts would have been blocked by debris thrown down over countless years.
The rock face I climbed wasn't very steep at all but looked it from the filmed angle. The final climbing and falling sequence was done about 5 feet above a sandy beach.
Just to clarify, the video is intended as humour with the punchline at the end.
Obviously most of my uploads are related to puzzles but sometimes I want to upload other stuff. I have never stated the channel is purely for puzzles.
