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:
“While this America settles in the mould of its vulgarity, heavily
thickening to empire,
And protest, only a bubble in the molten mass, pops and sighs out,
and the mass hardens,”
—Robinson Jeffers (1887–1962)
“O thou undaunted daughter of desires!
By all thy dower of lights and fires;
By all the eagle in thee, all the dove;
By all thy lives and deaths of love;
By thy large draughts of intellectual day,
And by thy thirsts of love more large then they;
By all thy brim-fill’d Bowls of fierce desire,
By thy last Morning’s draught of liquid fire;
By the full kingdom of that final kiss
That seiz’d thy parting Soul, and seal’d thee his;”
—Richard Crashaw (1613?–1649)
