Precisely. With no seed crystal it had nothing to grow on and would remain in saturation. My hope would be that somehow the laser would crystalize the solution in a thin layer. Who knows? Might be like shooting honey and never crystalize because we are also heating. Either way it turns out yummy for the kids.
