The thing I find interesting about questionable engineering clips like this one, the ramp-van, and the roof-slide is that once it's built and someone volunteers to try it out on camera, it's immediately PoE-worthy regardless of the outcome.
Once you make flamethrower attachments for your hands, it doesn't matter if you set your parent's garage on fire and end up in the hospital, or go out on halloween and safely entertain your friends for a few hours. PoE loves you either way.
