Why are some people calling this a tutorial in the comments section? There are no instructions, no measurements of the bottle or cardboard, no mention that the type of wiring or battery you use or whether or not he has a third-party controller, this just doesn't seem to me like tutorial at all. And if that's what the Creator was going for, he did a shit job at making a short tutorial cuz he didn't explain a goddamn thing. But that's assuming he was even trying to make this a tutorial.
