The Contraption That Can Really Tie One On

Why Knot goes:

Ktchtchtchtchtch.

"Phew! Yes!" (Goldstein exhales.)

He has written a maintenance book for the museum to care for Why Knot. It has diagrams and instructions. "If I stay at this museum, I'm going to have a heart attack! I gotta get this thing out of here and have a life," he says. And then, moments later: "I may want to make that knot tighter." But it's too late, since the machine is already congratulating itself. Why Knot, a true creation of the 21st century, knows how to clap when it's finished the job:

Thonk-thonk-thonk-thonk.

Thonk-thonk-thonk-thonk.

Thonk-thonk-thonk-thonk.

Thonk.

Stone's gaze lingers on Why Knot. "It's going to be sad to see it go," she says.

"It's going to be traumatic," says Goldstein, who will drive his creation to Philadelphia next week. "Gonna be like empty-nest syndrome."
