  1. One of my end projects for my chemistry degree was making luminol. Now if you combine luminol with hydrogen peroxide it will light up bright blue in contact with blood. This is also how they find spots of blood in a crime scene.

    This works because blood will speed up the decomposition of hydrogen peroxide as seen in the video above.
