I’m currently reading What If? by xkcd’s Randall Munroe. It’s pretty great. One of the sections elaborates on what would happen if you collected all of the elements of the periodic table in little cubes and put them together, as arranged in the periodic table. What unfolds is, obviously absurd given the lack of reality, but fascinating. One of the chemical reactions mentioned is related to the video above, describing what happens when gallium and aluminum hang out.
