Hi, Ivan:<br /><br />You could use "SNAP!" It also suggests a snapping of fingers as well as a spark. Or "CRACK!"I've heard&nbsp;people&nbsp;say "BANG! and then it happened" but I don't think that's appropriate&nbsp;here.<br /><br />I would go with SNAP! (as in we clicked).<br /><br /><br />BFN - George&nbsp;
