When a charged rod is brought near a stream of water comine out of a buret. the water is oulled toward the rod.' If the dekonstration is iepeated with'a nonpolar liquid such as cvclohexane. the rod has essentiallv no effect on the stream df liquid. his demonstration is avery convincing illustration of the ~ o l a r i t vof the water molecule. In 1879,- ~ a ~ l e published i ~ h his observations entitled "The Influence of Electricity on Collidinp Water D r o ~ s " In .~ atmosphe;icelecthe interveningcentury, the~importance~f tricity in the formation of precipitation has been investigated.3 The remarkable demonstration noted below, a logical extension to the one noted by Chang', has become known as the Ravleieh Fountain.
