I guess you could do it in space as long as you could have a sphere of molten glass floating, then immediately surround it with water from all sides. My reasoning is that the tail is formed because the molten glass is dropped into the water, hence forming the tail. So if you could have a sphere and cool it down from all sides simultaneously then it should form a sphere based version. Of course there's also a chance of explosion.
