BUBBLE LIGHTS made from scratch

Bubble lights are mesmerizing things to watch, up there with lava lamps as one of the nicer aesthetic creations of the mid-20th century. [Tech Ingredients] made a decision to head into the lab to whip up some of their own design, taking things up a notch beyond what you’d typically find in a store.

Bubble lights have a liquid inside glass that is held under a vacuum. This reduces the boiling point of the fluid, allowing a small heat input to easily create bubbles that float to the top of the chamber inside. The fluid used inside is also chosen for its low boiling point, with [Tech Ingredients] choosing dichloromethane for safety when using flames to work the glass.

The video shows off the basic glass working techniques required to make the glass bubble tubes, as well as how to build the bases of the bubble lamps that light the fluid up and supply the heat to create bubbles. The use of different materials to create nucleation points for the boiling fluid is also discussed, giving different visual effects in the final result. It’s a terrific primer on getting started building these stunning decorations yourself.

Bubbles are pretty things, and with different techniques, we’ve even seen them used to make displays. video after the break.
