The perfect xmas gift for a budding young Dr Evil.
In 1951, A.C. Gilbert, inventor of the ERECTOR set, released the U-238 Atomic Energy Lab. Using real radioactive materials, one could witness mist trails created by particles of ionizing radiation.
The set included four Uranium-bearing ore samples, and originally sold for $49.50.
