A Burning "Infofuse" Can Transmit Messages Via Colored Flames

"LOOK MOM NO ELECTRICITY." That was the first message conveyed by a rudimentary new communication system that researchers are calling the "infofuse." In a new study, researchers printed patterns of three different flammable metallic salts on a nitrocellulose fuse and then set the fuse on fire. As it burned, it emitted pulses of different colored light that can be interpreted with a Morse code system. In the study, published in the Proceedings of the National Academy of Sciences, researchers explain that they
