The effect of a surrounding, dielectric, liquid atmosphere on the dynamic of a suddenly electrified liquid drops is investigated. The dynamics of the electric droplet disruption is, surprisingly, varied modes. The electrically elongated meniscus in some circumstances results in the well-known tip streaming (with and without whipping instability); in others, the meniscus simply split in two (splitting mode) or the meniscus tip curbs developing radially in some sort of "splashing" (splashing mode).
