M’s Pyramid Trap

I asked M to play with K one morning so I could get cleaned up and dressed.  When I returned to check on them, she was singing in the chair, and he was testing his pyramid.

He didn’t have a way to make the ‘thieves,’ set off the cylendar themselves,

But they were only blocks themselves.  We’re just past King Narmer unifies Upper and Lower Egypt, can you tell?
