This pendant commemorates April 19, 1943, when Swiss chemist Albert Hofmann took a bicycle ride home from his laboratory in Switzerland after a self-experiment with a compound he had synthesized. The ride, later known as Bicycle Day, became a landmark in the history of scientific discovery and is remembered as a pivotal moment in 20th-century research into human consciousness.

Crafted as a tribute to that historic day, this piece marks a quiet but significant chapter in the story of modern science.
