We love chemistry, so we really light up when we talk about this product created at ThinkGeek: Radioactive Elements Glowing Coaster Set. Featuring the atomic number and isotopic mass of the most stable or common isotope for their respective radioactive elements, these pressure-sensitive coasters light up when you put your drink on them. Choose to set your drink down on: Radium-226 (Red), Plutonium-244 (Blue), Uranium-238 (Green) or Thorium-232 (Orange).
Set of four comes in a box with the radioactivity warning symbol. Batteries included.
