Understanding Eye Agates and Their Formation

The video explores the intriguing appearance of eye agates, which resemble human eyes due to their formation process. Agates form when silica-rich fluid fills rock gaps and crystallizes, creating banded patterns. These rocks are often marketed as mystical objects, with enhancements like polishing and dyeing to enhance their eye-like appearance. The video also highlights Brilliant, a platform for interactive STEM learning.
