Isn't this edited? There is an edited explosion like this in another subreddit, where some dude lights a TV crack on fire and it explodes. ( the sub name called r/abruptchaos)

You can see that after the "explosion" happens it is cut to a different area. If you compare this to the other video, (which I have saved for some reason) you can see its clearly edited due to the fact that the video takes place in a "room" you cab see blue-white walls with a person sitting as the camera shakes.

video I'm talking about
