Young's Demonstrative Translation of Scientific Secrets · Chapter 311568. An Illuminous Bottle
This chapter is not translated yet. You are reading the original.
By putting a piece of phosphorus, the size of a pea, into a phial, and adding boiling oil until the bottle is a third full, a luminous bottle is formed; for, on taking out the cork, to admit atmospheric air, the empty space in the bottle will become luminous. Whenever the stopper is taken out in the night, sufficient light will be evolved to show the hour upon a watch; and if care be taken to keep it in general well closed, it will preserve its illuminative power for several months.
