Japan sets off fireworks in space to study airflow activities (Figure)

Yes, but it's not the people above who say that dazzle is aerobic. Anyone with a little brain knows how to put oxygen in fireworks. If it is closed, how to study the airflow?

Actually, it was because potassium chlorate was added to the fuse and fireworks. When heated, oxygen will be decomposed and reused. At this time, some people will ask, how did it ignite? In fact, it was ignited by an electronic spark. That's it.
