When i saw this old comic book ad I guickly googled it to see if it was a real ad. Distributed by Kix Cereals (15 cents plus a boxtop), the instructions stated:
"You'll see brilliant flashes of light in the inky darkness inside the atom
chamber. These frenzied vivid flashes are caused by the released energy of
atoms. PERFECTLY SAFE - We guarantee you can wear the KIX Atomic "Bomb" Ring
with complete safety. The atomic materials inside the ring are harmless."
When the red base (which served as a "secret message compartment") was taken
off, and after a suitable period of time for dark adaptation, you could look
through a small plastic lens at scintillations caused by polonium alpha
particles striking a zinc sulfide screen.
Seriously, how cool was the 1950's ???
