This is really nice! Actually the borax may hydrolyze to boronic acid, and react with the carbonyl groups on turmeric, to give a dimeric complex which account for a bright red color

By the way, we had established a new tag #sciencepic for science pictures, and that would be really great to have more original photos from you!!!
Feel free to use the tag, you may have a look here to know more about it :D

Meanwhile, steemstem are holding a #sciencefair soon. Feel free to join if you have other interesting experiments to show :D
