AlkaliMetalsMod
What's This Mod?
Ever wanted to add a real-life science experiment to Minecraft? This mod adds all the alkali metals from the periodic table, which react realistically to rain and direct water contact. Each ingot—from Lithium to Cesium—can be obtained throughout the Overworld and smelted down into reactive ingots. In addition, Francium (one of the most reactive elements on the periodic table) can be found in the Nether. It reacts with the air instantly, eventually reaching its half-life and decaying into Astatine and Lead.
