Query: An old favorite that engages an 8 year old

My grandson was completely engrossed in this erector set as soon as he opened it. I was concerned that it might be overwhelming to have so many little parts, but soon he was building a catapult and even making some adaptations! He even enjoyed putting all the little parts in their proper storage compartments. The carrying case was well made, too. Best of all, we can add to it over time as his interest and skill improve.
