The Bike That Wouldn't Stay Broken

Aunt Ruthie ran a bike shop out of the garage, and she did not believe in miracles.

"Somebody's paying me to break things," she told Soren, wiping grease from a wrench. "Which is the first job I've ever had that made no sense."

On the workbench sat a metal frame she called the tester. It held a flat gray strip clamped at both ends, with a little wheel that turned a screw to pull the strip tighter and tighter until it split. There were forty strips in a box, all the same. A company had sent them. Ruthie was supposed to stretch each one until it cracked, write down the number where it broke, and mail the numbers back.

"They didn't say what it's for?" Soren asked.

"They said proprietary." She said the word like it tasted bad. "Which means mind your business. So I break their strips and cash their check."

Soren picked up a strip. It was cool and slightly waxy, like a candle that had decided to be plastic instead. He held it to the light. There was something inside it, a faint cloudiness, like the strip was full of the tiniest bubbles a person could imagine.

He cranked the wheel. The strip stretched, went pale along a line across its middle, and snapped with a small dry tick. He wrote the number Ruthie told him to write.

Then the shop phone rang and she went to argue with a supplier about tire tubes, and Soren was alone with the broken strip.

He set the two halves down on the bench, cut ends touching, the way you leave a torn page hoping it will forgive you. He did it without deciding to. He just did not like the gap.

He got his notebook and drew the tester. He drew the little wheel and the way the crack had crossed at an angle instead of straight. He drew the cloudiness inside the strip. Under the drawing his pencil made small circles, tiny bubbles, and he sat looking at them.

Bubbles. Something inside the strip.

He went back to the broken halves to look at the cut edge again.

They would not come apart.

He picked up the strip and both halves lifted together. Where the crack had been there was now a thin shiny seam, wet-looking, like the strip had drooled along its own wound and the drool had gone hard. He pulled. It held. It held better than paper glue, better than anything he could have done with the tubes of adhesive on Ruthie's shelf.

He had broken it eleven minutes ago. He had watched it snap. Now it was one strip again with a scar.

Soren sat very still He took a fresh strip and cracked it and left the halves apart, not touching. He took another and cracked it and pressed the halves together and held them with a rubber band. He wrote down the time next to each one. Then he cracked a third and looked at the pale line before it snapped, closer, closer, until his nose nearly touched it.

At the pale line, right before the tick, the cloudiness changed. The tiny bubbles along the stress line went from little round shadows to little smears. They were breaking. Whatever was in them was coming out.

He thought about a scab. He thought about the time he split his knee on the driveway and his mom said the body sends stuff to the cut to close it, and how he had lain awake wondering how the blood knew where the hole was.

The blood did not know. The hole opened the blood.

That was it. That was the whole thing. The strip did not know it was cracking. The crack itself tore the bubbles open, right where the damage was, exactly and only where the damage was, and the stuff inside spilled into the gap and hardened. You could not aim it. You did not have to. The break did the aiming. Wherever the material hurt, that was precisely where the medicine already was, waiting in a million little sealed drops for the one crack that would ever reach them.

Soren checked the strip he had left apart. Still two pieces. Nothing to bridge across the empty air, so nothing healed. He checked the one he had banded together. Already a seam.

Aunt Ruthie came back muttering about tire tubes and stopped when she saw his face.

"You look like you swallowed a bee," she said.

"They're not paying you to break them," Soren said. "They're paying you to find out if they stay broken."

She frowned. He handed her the strip he had snapped eleven minutes ago and told her to pull it apart.

She pulled. Her eyebrows went up. She pulled harder, the way adults do when they don't trust a thing, and the strip stretched but the seam held, and she looked at it, then at him, then at the box of forty.

"That's not glue," she said slowly. "I didn't glue it."

"It's inside them," Soren said. "In little bubbles. Breaking it is how you turn it on."

Ruthie set the strip down like it might be listening. "So the number I'm supposed to write."

"Isn't where it breaks." Soren's hand was already moving in the notebook. "It's whether it can break twice. In the same place."

He took the healed strip back and put it in the tester. He cranked the wheel. Ruthie leaned in. The seam took the strain, held, held, and then a new pale line appeared, not at the old scar but a finger's width beside it, in fresh material that had never cracked and still had all its bubbles.

It snapped there instead. The old wound was now the strongest part of the strip.

Ruthie laughed, one short surprised sound. "It's harder to break where it already healed."

Soren pressed the two new halves together and reached for the rubber band, then stopped, because he wanted to see how many times.

He cracked the strip again in a new place, and again, working down its length, each break a little farther along, laying scars like knots in a rope, and every time he set the halves touching the strip drank its own tiny bubbles and closed.
