Domino trick shot

I found the Domino trick shot challenge a little bit hard because the dominoes would keep on falling over as I was setting it up. The Lego mini-figure that I put at the end keep on falling over causing the Dominos to fall over. When I shot the first Dominos with a Nerf gun some of the Dominos fell off the side of the ramp and down to the stream below of them, that's why you will see me push some over with my finger. but otherwise it'll worked pretty well. Here is my domino trick shot challenge Link .Have you ever done a Domino trick shot?
