This audience was waiting for a geyser
to start erupting.

What I hadn't realised was that this particular geyser
could be induced to start by putting 300 grams
of washing powder down its throat.

The advantage of this was that it could be advertised as
coming to life at 10.30 every morning.

Actually, the guide gave a very good description
of how the washing powder worked.
It had to do with surface tension.
