The Ames Room

The distorted room was named after ophthalmologist Adelbert Ames, who invented the optical illusion in 1934. The floor, ceiling and side walls of the room are trapezoidal in shape but when viewed from a specific fixed point it appears to be rectangular.

We built this for the 2011 Christmas Lectures. See it in action in this clip from the lectures, or hear Andy talk about making it here.

Transformation of a supersaturated solution into solid crystals

It just takes one small nudge to spark the transformation of a seemingly stable liquid into a solid. The liquid – a supersaturated solution of sodium acetate – consists of water with more dissolved sodium acetate salt than can be stably sustained. Drop in a salt crystal and provide the kick needed to start the transformation into the more thermodynamically favourable solid state.

But if the solid state is more thermodynamically stable, why does it exist as a liquid at all? It’s to do with scale: the solution is only better off as a solid at the macroscopic scale – the scale of the whole solution. On a microscopic scale, the individual crystals are not thermodynamically favourable, so until you start it off with a salt crystal (which is, relatively, a huge disturbance), the transformation won’t begin.

Watch the full ‘Tales from the Prep Room’ film for more explanation, extra footage, and the curious problem we encountered when filming.
