On a recent snowy, spring day, the Bean spent many hours and more than a few tears trying to create an elevator out of his Legos. He learned about pulleys and cranks and fulcrums, without really calling them by name.

I’m not sure that he knew he was practicing a form of science that his Mama never even studied. But in the end, he pulled off a fully functioning lift for the Lego guys who don’t feel like taking the stairs.
