When grandchildren challenge you
But what am I saying: great?
Gigantic Mike!
Playing and learning with your grandchildren is something fantastic that honors you.
I did lots of experiments with my son when he was little.
While playing he learned many notions of physics and chemistry.
We also played with electricity (low voltages).
Good, good, good.
P.s. I really like the raft, congratulate your nephew.
I'm glad he also knows Italian.
Knowing languages is an asset for himself.
