>> cling there under surface tension = Static charges. When a walk in wool socks on a wet carpet my socks pick up water. When I walk on a dry carpet my socks pick up electrons. >> expand, and break open its insulation = an arc causes by too much electricity in too thin a pipe. >> it doesn't evaporate and condense on cold surfaces = electro vapor deposition aka physical vapor deposition
