A £900,000 mirror sculpture destined for a square in Nottingham, UK, will have to be shielded to prevent it focusing the Sun's rays and barbecuing passing birds. Anish Kapoor's
highly polished concave steel mirror is six metres in diameter. Direct sunlight hitting the mirror would be focused into a narrow beam of light as hot as the surface of the Sun, says astronomer Michael Merrifield of Nottingham University.
