A spinthariscope is a device used to demonstrate the randomness and variability of nuclear decay by employing a Geiger counter-like detection method. It uses a thin sheet of zinc sulfide coated on the inside of a glass tube, and the zinc sulfide acts as a cloud chamber, causing a cascade of sparks to appear, which correspond to the decays of alpha particles, beta particles, or gamma rays emitted by radioactive ions contained in the tube. The tube is then spun around quickly, causing the apparent position of the sparks to vary rapidly and randomly, and the user can observe a visual representation of radioactive decay.
Spinulescent refers to something that is covered or characterized by fine, pointed outgrowths or spines, such as tiny projections or tubercles on the surface of an organism.
