In the museum, there is a section on light, and this huge structure demonstrates fibre optics. It’s sort of like a jungle gym, from what I could gather. I was too tall to play on it. 🙁
My version of the TARDIS going through the time vortex! (Or another one, that isn’t coloured…)
I just LOVE the pretty colours in this, so I cropped the original picture in two ways.1. More TARDIS, less colour.
2. More colour, less TARDIS.
