WATCH: 'Sub-zero bubble blowing'

A woman in the frigid temperatures of Michigan tested out what she called "sub-zero bubble blowing." 

Video posted to Katy Hallgren's Instagram page shows a closeup of the bubble sitting on the wand, freezing to it.

In a second video, she blows the frozen bubble, which bursts and shatters into pieces in slow motion. 

Most of the country is experiencing freezing temperatures, including now parts of Florida, which are under a winter weather warning.
