I am unsure if you could do it that way, but the water is likely mixed with copper, judging by the color.

- MaMa 16y agoProbably just blue dye to make it visible to the camera
- Lost_BiomedE 16y agoAgreed, it is likely for the camera. A lot of blue dyes for water fountains and such are copper sulfate. Dyes for tanks or fish ponds are increasingly methylene blue, food dye. I thought I would just extend the poster's thought experiment, not imply that magnets were indeed used.
