Uranium Doped Marbles
Radioactive Uranium Doped Glass Marbles.
These marbles contain approximately 3% Uranium ²³⁸ ( by weight ).
This small amount of Uranium is added to the glass while it's still in the furnace and in a molten state.
As the Uranium dissolves into the red-hot glass, it takes on the tell-tale pale green color of Uranium Glass.
Because of the added Uranium in the glass, the marbles glow brightly under Ultraviolet light ( Blacklight ).
The small amount of radiation that the glass emits will also register on sensitive Geiger Counters.
The marbles do not emit high or dangerous levels of radiation, and are completely safe to handle.
A small sample of Uranium ore (the type used to make this particular type of glass) is included. 
A very unique conversation piece.
FREE! - A piece of Uranium ore comes packaged with your marbles!
