Alessandro Volta's theory of contact tension considered that the emf, which drives the electric current through a circuit containing a voltaic cell, occurs at the contact between the two metals. Volta did not consider the electrolyte, which was typically brine in his experiments, to be significant.
Victoria Falls Bridge is the location for a 111 meters (364 ft) bungee jump. The Victoria Falls Bridge crosses the Zambezi River just below the Victoria Falls. The bungee jump operates off the Victoria Falls Bridge and has a 100% safety record. Over 50,000 people have bungee jumped from this location.
