This is really amazing :)
Wow! It's impressive! A bit dangerous, but cool. Greetings from Spain!
Our posters bought commercial smoke bombs and took the outer casings off. They did not mix or produce anything you are seeing here.
If you note, most of them 'burn' instead of smoke. That's because the outer casing is needed to keep too much oxygen from rushing to the ignition.
