m child is 12 but he thinks like alber einstine coming up with shit that most 12 year olds dont think of or about he is always talking about building all these crazy cars and guns and stuff but he goes down to every little detail of it and it sounds likes most of it is possible he does blue prints on it and studies it then usually BUILDS IT!so would you say he is gifted or just an average kid.and most of the stuff he builds is as complicated as car motors if not more complicated.it isnt stuff that most 12 yr olds think of.
