How might some of the exhibits have been dangerous?
Modern sculpture rarely surprises us any more. The idea that modern art can only be seen in museums is mistaken. Even people who take no interest in art cannot have failed to notice examples of in gardens, and outside buildings and shops.We have got quite used to them. Some so-called 'modern' pieces have been on display for nearly eighty years.
In spite of this,some people-including myself-were surprised by a recent exhibition of modern sculpture.The first thing I saw when I entered the art gallery was a notice which said:'Do not touch the exhibits. Some of them are dangerous!' The objects on display were pisces of moving sculpture. Oddly shaped forms that are suspended from the ceiling and move in response to a gust of wind are quite familar to everybody. These objects, however, were different. Lined up against the wall, there were long thin wires attached to metal spheres. The spheres and been magnetized and attracted or repelled each other all the time. In the centre of the hall. there were a number of tall structures which contained coloured lights. These lights flickered continuously like traffic lights which have gone mad. Sparks were emitted from small black boxes and red lamps flashed on and off angrily.It was like an exhibition of prehistoric electronic equipment.These peculiar forms not only seemed designed to shock people emotionally, but to give them electric shocks as well!
