We love chemistry, so we really light up when we talk about this product created at ThinkGeek: our 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)
  • Thorium-232 (Orange)

Set of four comes in a box with the radioactivity warning symbol. Batteries included.
