From Roger Morgan, London, UK
You report on Earth’s lowest relative gravity spot, just south of India. This brought to mind an account of a UK equivalent: the Warlingham gravity anomaly in Surrey. This was found in the 1950s, with interest in the press and some reports implying a complete absence of gravity (1 July, p 13).
Apparently, a masonic lodge out for a day found themselves in nearby Caterham. After lunch, and a few drinks, one suggested they investigate the anomaly. This was taken up by the party, who, grabbing a number of plates, went to the nearest railway bridge to drop them to see if they hovered or floated slowly down. Needless to say, the result was a pile of broken crockery.
