My son (10 years) to this experimentation Box wished birthday because he very interested in physics experiments. Unfortunately, but many experiments are already known and very simple, so you do not need to this mini-lab. For him, there were few surprises and I think that for the specified age-but a few trickier things could be there. Have we unfortunately expect more, therefore only 3 stars. Apart from the workmanship is good and it has every experiment works.
