Pyridium is a NDSR (Non-Decaying Synthetic Radioactive) element on the PLUX Element Table. It is number 157 and it is liquid at room tempature. It burns through most anything (as a liquid) and turns it into a gas. Although it may not seem true, Pyridium has a hot freezing point: -20 degrees celsius. If you freeze pyridium, it stops burning and turns into an alternating cold-hot powder. Major projects like the Beta Plus missile are used to melt strong materials.
