Amazing to watch once... there people have to do it 10000 or 100000's of times, in a lifetime.Just think America gave away all those manufacturing jobs, just think how better off we would be if we didn’t, less unemployment for one thing better mental health throughout society etc...etc...,our politicians sold us out and now we are paying the price.If you aren't amazed at the skills and ingenuity of these products you are brain dead. Just fantastic.
