The rods have the same colour as lightning. But their glow is steady, like a gas lamp.

The ceiling is low. Other things dangle from it. Directly above me there are nine balls of different sizes hanging like Christmas decorations. Four small spheres hang in a row, coloured grey and white and blue and red. Then there are four big spheres. The second one has rings around it like Saturn.

That's what they are, models of the planets! But every one knows there are eight planets. What's that tiny little dark one after Neptune? Perhaps it's an escaped moon.
