Like a great revolutionary orator, a Polish artist addresses a crowd in front of Somerset House. He storms towards a shop window smashing the glass. Inside is a block of an extremely unstable substance at which he hurls a handful of coarse salt. A poisonous vapour is emitted.
How can he do this and survive I wonder?
The audience is spellbound and flocks towards him in admiration. Everyone now has their face bandaged as protection from the fumes.
