Here is a more thorough scientific description on what is actually happening.  They get into the physics and it’s very informative:

In the paper, the team described a “bubble-bursting cascade”.

“When one of these daughter bubbles ruptures, a ring of even smaller bubbles forms,” the researchers wrote.

Eventually, the daughter bubbles are sufficiently tiny that they rupture to form sharp “jets” that propel small aerosol droplets into the atmosphere.

James Bird from Harvard University, who led the research, explained that his main interest was in the fundamental physics of how bubbles behave. But his discovery could eventually help to fine-tune many manufacturing processes.

“Where small bubbles are detrimental, such as in glass manufacturing, our results provide insight into how the parameters might be tuned to reduce the daughter bubbles,” Dr Bird explained.

Ah now that we know how that works we can enjoy the video.  Thanks for watching and keep on the lookout for more cool science experiments from us.
