I had to laugh at the time and effort that must have gone into this - a scale model of the A-10 Thunderbolt II ground attack aircraft, complete with a built-in Nerf gun firing soft foam balls! The first part of the video shows the plane in action; the second part shows how it was built and 'armed'. Watch it in full-screen mode for best results.
Someone put a lot of effort into that. I hope the fun was worth it!
