'Jane Grey' reference
Series 1, episode 2, "Water"
In Experiment 2, they use a "Jane Grey's pipe" to transfer nitrogen gas into a beaker of water (to let it "mafipulate" for five minutes).
Surely the tube is not actually called a "Jane Grey's pipe." What does it mean?
But the most curious thing, what is the significance of the silver box and the harpsichord music when the scientist gently puts away the pipe?
(Ok, I see that Jane Grey is a Queen of England. But I'm American, and a poor student of history, so I have no other context to place this in.)
