The Wrong Way to Stretch

"Pull it tight," Maya said. "I need to see where it rips."

Soren pulled the dog harness straps until they went thin and pale under his fingers. The strap narrowed, the way every strap does, and right at the worn knee it gave a little crackle of threads letting go.

"It always tears in the same place," he said. "Where it gets skinniest when you stretch it."

"Because skinny means weak." Maya dug through the bin of scraps Soren's uncle had dumped in the garage. Foam, mesh, a few stiff gray sheets with little hexagons cut into them like a honeycomb that somebody had stepped on. "We need something that doesn't get skinny."

"Everything gets skinny when you pull it. Rubber bands. Gum. Your own skin." Soren stretched the harness again to prove it. "It's just what stretching is."

Maya picked up one of the gray sheets and held it by both ends. "Says who."

"Says everything that has ever been stretched."

She pulled.

Then she stopped pulling and looked at the sheet, and then she looked at Soren. "What," Soren said.

"Pull this one." She handed it over. "Watch the middle. Not the ends. The middle."

Soren took the gray sheet by its two short edges. He pulled it slowly, the way he pulled everything, watching for the thing that would behave wrong before the thing that behaved right.

The sheet got longer.

And the middle got wider.

He stopped. He let it relax. The middle pulled back in. He stretched it again and the middle pushed back out, fat in the center, like the sheet was taking a breath.

"That's the wrong way," Soren said quietly. "That is the completely wrong way."

"I know."

"Pull harder, it should go skinnier. Everything goes skinnier."

"I know. Do it again."

He did it again. Six times, actually, holding the same spot in the middle with his thumbnail to be sure he wasn't imagining the spread. Each time, the harder he pulled the ends apart, the more the middle bulged out against his thumb.

"It's pushing back into my thumb," he said. "It's getting fatter where I'm pulling it longer. That's not possible."

"It's happening, though," Maya said. "So it's possible."

Soren held the sheet up to the bare bulb hanging over the bench. The honeycomb cutouts weren't honeycombs. They were little arrow shapes, hexagons folded inward, each one pinched at the waist like a bowtie. When he relaxed the sheet, all the bowties sat squeezed tight. When he stretched it, every single bowtie swung open at once, and opening sideways was the only way they could go.

"Look," he said. "The shapes. They're all bent inward. When you pull, they don't have room to get thinner. The only thing they can do is unfold. And unfolding makes them wider."

Maya leaned in over his shoulder. "So it's not the stuff. It's the holes."

"It's the holes. It's the pattern of the holes." He stretched it once more, watching the bowties open in a wave down the sheet. "Same plastic as anything. Somebody just cut it so it can only get wider."

Maya took it back and pressed her thumb hard into the center, and the sheet pressed back, firm, a little stubborn. "Punch the middle of a normal thing, it dents. The stuff runs away from your finger."

"Right. It gets thinner where you push."

"But this." She pushed again. "This pulls toward my finger. It crowds in. It gets thicker right where it's being hit."

They both went still over the gray sheet.

"That's armor," Soren said. "That's the whole thing about armor. You hit it and it gathers up to meet you instead of running away."

Maya was already across the garage at the bin, holding two more scraps up to the light, checking their cutouts. "My uncle didn't tell us what these were," Soren said.

"Your uncle thinks they're garbage. They went in the garbage bin." She found a curved one, a piece shaped to wrap around something, the bowties printed even smaller and tighter. "This one's for a body part. It's bent to fit. Look how it's curved."

"Or a wing," Soren said. "Or a tube. Anything that has to wrap a corner and not split when the corner bends." He turned the curved piece over. "A flat normal sheet hates wrapping a ball. It puckers. It bunches up. But if it spreads wider exactly where it's stretched the most, it could just lie down smooth over a curve."

"Like skin," Maya said. "Real skin. Like something growing."

They looked at each other.

"Inside a person," Soren said slowly. "A patch. You'd want a patch that gets fatter when the body pulls on it, not thinner. Thinner is where it tears. Thinner is where the harness keeps ripping."

Maya laid the gray sheet over the worn knee of the dog harness. She stretched the whole thing across the bench, and the strap underneath went thin and pale and ready to crackle, and the gray patch on top of it went the other way, swelling fat and tight exactly across the spot that always tore, exactly where the strength was needed most, getting stronger in the precise place everything else got weak.

"It's protecting the worst part," she said. "It's strongest right where the other thing is failing."

Soren reached for his notebook and drew the bowtie, pinched, and then drew it again, swung open. He sat with his pen not moving.

"Somebody had to figure out you could cut a hole that makes a thing do the opposite," he said. "That the rule everybody knows isn't the only rule. It's just the rule for the shapes we usually use."

Maya pulled the two ends of the harness as far apart as her arms could reach. The gray patch in the middle pushed out toward the ceiling, swelling, reaching back, fattest exactly where she pulled it hardest.
