Coasters are often a forgettable part of home decor, but ThinkGeek has created a set that’ll make you eager to set down your drink. Unlike many tiny trays, their Radioactive Elements Coasters come with a playful bonus feature: they light up when touched. Pressure sensitive, they glow bright colors as your favorite beverage graces their surface. This adds some glitz to your decor, and it’s perfect for parties, too—guests will easily remember what shining element is theirs.
When not in use, the coaster set offers trivia about Radium, Plutonium, Uranium, and Thorium. Each square is modeled from the Periodic Table and displays the name, atomic number, as well as the isotopic mass of the most stable (or common) isotope. All of the radioactive elements are technically unstable, but unlike their namesakes, having these coasters means that your tables are safe from any volatile drinkers.
ThinkGeek’s Coaster set is currently sold out on their website, but it’s still available through Firebox.com—just in time for your next gathering.
