Lyndey's demo is part of a project with some science classes for visitors to the venue - they will learn that Cragside was one of the first places to make use of electricity. One of the devices they first powered was a copper light with a curious and distinctly unsafe method of passing the electricity from the source to the bulb.
In our mock-up, users can see some copper jugs with 3D-printed modifications and they're a bit safer than the original!
