Exercise ball

In my room I have a blue exercise ball that I like to sit on or put my feet up on or basically do anything but exercise with. While looking at this ball, I remembered a video I had seen a little while ago of a child getting hit very hard with an exercise ball. The video is below if you haven't seen it. 
Basically, this is one of the dumber things I've seen, but the kids obviously weren't well versed in the concept of momentum. The smaller child was gonna absorb most of the force from the collision as the larger boy was traveling much faster and I assume has greater mass. As a result of this, the child would travel in a relatively high velocity in the direction that the exercise ball boy was running. They had the right idea that the child would act like an angled projectile after the collision as they had safety bean bags set up to break his fall, however they overestimated how quickly the boy would be accelerated downwards, and I don't think they realized how close the wall was. As a result of this, we have this video.
