What you will receive You will receive a 1.8ml glass vial of high quality europium based phosphorescent (glow-in-the-dark) powder. As seen in pictures The facts Produces a beautiful true blue glow color. Great chemistry gift Amazing science gift Sweet Stocking stuffer, Christmas gift Fun teaching tool It is a difficult and expensive glow material to make due to the high cost of the exotic s Based on the Rare-Earth element Europium Europium powder can be recharged indefinitely just by holding it under bright light. (with the exception of extremes) Unlike other glow in the darks. 30 hours of glow time after being fully charged.
