I was drawn to this originally based on the color — black soap isn’t something I see everyday. But now after reading the ingredients list, I’m convinced this might be a wonderful smelling soap.
The Slow Mo Guys got their hands on a Phantom v1610 which shoots 720p video at 18,000 fps. That’s slow enough to show a soap bubble popping in the length of 30 whole seconds (obviously, this process usually happens in a fraction of a second).
