From Paul Champion
The Grimbledon Down cartoon by Bill Tidy that used to appear in Â鶹´«Ã½ answered Rudolf Pfeiffer’s question over whether anyone has previously tried making diamonds out of drinks (21 June, p 29). In 1986 it was found that ethanol vapour would form a thin layer of diamond under certain conditions. Shortly thereafter Treem, director of the Grimbledon Down research complex, confronted a member of staff for requisitioning a bottle of the best malt from the social club (20 March 1986, p 65).
