When is a ball not a ball?

When is a ball not a ball? - student project

Here is part one bouncing ball. It did start off as a ball! Just ended up to be robot in bouncing car. Have not quiet finished the moon one but I wanted to show it so far. Having not able to change the little orange guy to a robot I had to think out side the box . Will upload the last one after I finish watching and tweaking it .
