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)
“Glorious the northern lights astream;
Glorious the song, when God’s the theme
Glorious the thunder’s roar:
Glorious hosanna from the den;
Glorious the catholic amen;
Glorious the martyr’s gore:
Glorious—more glorious is the crown
Of him that brought salvation down
By meekness, called thy Son;
Thou that stupendous truth believed,
And now the matchless deed’s achieved,
Determined, Dared, and Done.”
—Christopher Smart (1722–1771)
