From the “my kid is a genius at age six” file
So it’s Sunday morning. I’m on the potty (and yes, we all call it a potty,) when Ford comes bashing into the bathroom with a lego car. It’s got an armature attached to one side and has a cylindrical magnet encased in plastic (with one exposed face) clicked onto the end. He says to me:
“Look at this cool magnet piece I found in your lego box Dad.”
“That’s awesome.” I say. “What are you going to use it for?”
“I’m not sure. But it’s a north pole magnet.”
I blink a couple times and respond. “What do you mean?”
He looks at me with his bright eyes and pokes the exposed ceramic portion of the magnet.
“This is the north pole of the magnet. I know this.” (Serious gaze and nod.)
“How did you determine that?”
“Because when I try to touch it with the north pole of my other magnet it pushes back, but the south pole sticks to it” he explains like a patient, 3 foot tall teacher.
“Oh really?”
“Yeah. With magnets south only sticks to north and north only sticks to south.”
I blink some more. “So that’s a north pole magnet there.” (On the exposed face.)
“Yup.”
And Ford goes back down the hall to play (leaving the bathroom door open of course.)
Deductive reasoning at age six!
