Greetings fellow nerds. In this video we’re going to make a heart of iron wire appear to bleed when placed in solution. First get 100 mL of water and add to it 1 gram of potassium thiocyanate. Then add to it 1 mL of 12M concentrated hydrochloric acid and 1 mL of 30% hydrogen peroxide. Shake up the solution until completely dissolved. Pour out the solution into a dish and drop into it an iron wire that’s been shaped into a heart. Instantly the iron will appear to bleed as the chemicals dissolve the iron and produce iron thiocyanate that has a blood red color. A more dramatic approach is to hang the iron in the solution and view it from the side. And there you go. Yet another nerdy valentine’s day chemistry trick. This is a variation of the bleeding iron trick i showed in a previous video. Thanks for watching. In this video we’re going to make iron nails appear to bleed. In this video we’re going to make flowers glow in the dark under ultraviolet light with a fluorescent dye. In this video we’re going to break a heart with liquid nitrogen. In this video we’re going to set these valentine’s day candy hearts on fire using our favorite oxidant; potassium chlorate.
