Swan Neck Flask Experiment Hats
Main Tag:
Description: A detailed scientific illustration of a swan-neck flask with sterile golden broth, dust trapped in the curve of its long neck, set against a deep dark background. In 1859, experiments with swan-neck flasks showed that broth stays sterile when airborne dust cannot reach it, disproving spontaneous generation and strengthening the germ theory of disease. A gift idea for biologists, naturalists and life-science students, and a fitting piece for a study, lab or office wall.
