Abstract

The phenomenon of optical invisibility associated to refraction index matching is demonstrated by a series of laboratory photographs. Two pyrex glass recipients, one placed inside the other, are filled subsequently with sunflower oil, resulting in the optical disappearance of the smaller recipient. However, the presence of the smaller recipient can be revealed by using the fluorescence properties of the sunflower oil when inciding with light from a simple laser pointer.
