This is what happens when you mix Mercury(II) thiocyanate (Hg(SCN)2) and Ammonium chromate (NH4)2CrO4 and then set it on fire. I was honestly expecting the fiery volcano part, but at about 30 seconds in something… horrifying happens. The kids witnessing the experiment really make the video. “The kraken!!!!” (via The Awesomer)
