This video shows a sodium silicate solution with coppersulfate crystals at the bottom of the container. When waterglass is combined with a selection of different metals in solution (in this case copper sulfate), the waterglass would cause the metals to precipitate, forming stalacmites. This video was taken using interval timer shooting and coverted into a short movie.
It was an fair video, needed more FPS, and maybe a watch or timer so we know how long it toke the crystals to grow
