Bubble Lights
Bubble lights are a type of incandescent novelty light that acquired some popularity during the 1950s. Their main feature is a sealed glass tube with a colored bubbling liquid inside, created by the heat from the incandescent light. The fluid within the vial was originally a lightweight oil but now is methylene chloride for a more consistent bubble effect. While the idea was first demonstrated by Benjamin Franklin, the idea was adapted for use in Christmas Lights. They were invented by Carl Otis in 1935 who sold the patents to the NOMA Electric Corporation. There is a long story involving patent fights. Bubble Lights can still be purchased online and in stores to this day.

Famous quotes containing the words bubble and/or lights:
“If the bubble reputation can be obtained only at the cannon’s mouth, I am willing to go there for it, provided the cannon is empty.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“The cloud was so dark that it needed all the bright lights that could be turned upon it. But for four years there was a contagion of nobility in the land, and the best blood North and South poured itself out a libation to propitiate the deities of Truth and Justice. The great sin of slavery was washed out, but at what a cost!”
—M. E. W. Sherwood (1826–1903)
