What is this?
Still trying to figure it out
My son spotted the stapler and tried to figure out what it is based on functionality. He tried combing his hair but something did not seem right, then placed it next to his ear as he does to a phone, “Hmmm nah.” then he tried moving it like a toy car but the motion did not as smooth as it should.
It was interesting him watching him discover something by relating it to things he already know. The human brain, very fascinating
