Don't worry, these Radioactive Elements Glowing Coasters aren't really radioactive. They won't leach radiation into the icy cold beers they support. ... Or will they? Maybe that Thorium-232 won't just keep the rings off my mothers oak coffee table. Maybe it will turn me into the next Spider-Man! Or Radioactive Man from The Simpsons! You don't get a glow like that with normal isotopes running through your blood.
