The little jets of white stuff are subatomic particles right?

They're trails of gas charged particles leave behind. The particles are mostly muons which are leptons, like electrons. They're created in the upper atmosphere when high energy EMR (Cosmc Rays) collides with molecules of atmospheric gas. They aren't being created by radioactive decay, as there's no radioactive source present.

wow awesome XD

What are the little jets of white vapor shooting everywhere?

Radioactive decay, the biggest ones(lines) are mostly alpha particles, but other particles can also be detected.

that's not radioactive decay those are cosmic particles

and most interestingly, you are an idiot on a science video

that's only ur opinion.

great video!
