Its a bit simple, and repetitive (i.e. F1 cars go fast thanks to eighteenth century cannon technology is not quite true. And then saying again and again, wow, that went 25% further, wow, that went so much further, wow, that made such a difference!)
But, the tenuous connections aside its fairly interesting. If I had a child between the age of 8-14 it would probably help make them find engineering exciting, which I guess is its purpose.
