Electrical discharge machining (debris) to be carried away and the insulating properties of the dielectric to be restored. Adding new liquid dielectric in the inter-electrode volume is commonly referred to as "flushing." Also, after a current flow, the difference of potential between the electrodes is restored to what it was before the breakdown, so that a new liquid dielectric breakdown can occur. The erosive effect of electrical discharges was first noted in 1770 by English physicist Joseph Priestley. Two Russian scientists, B. R. Lazarenko and N. I. Lazarenko, were tasked in 1943 to investigate ways of preventing the erosion of tungsten electrical contacts
Electrical Water Pageant premiers of the updated version of the Disneyland Main Street Electrical Parade and new (but similar) Walt Disney World Main Street Electrical Parade used a new version of "Baroque Hoedown" updated by Don Dorsey. The original lineup of floats for the Electrical Water Pageant were: While the 1971 version of "Baroque Hoedown" would play along with the Electrical Water Pageant through 1976, Disney melodies were added to the track and some of the floats were repositioned and others completely changed in 1972; and remained that way through 1976. While the track was essentially the same as what was heard during
