On Ephraim’s fourth day of school, Ms. Little announced that they were going to visit the Van de Graaff generator. Ephraim’s face lit up. A Van de Graaff generator meant they were taking a trip to the Museum of Science in Boston to see the machine that re-created lightning. There couldn’t be one any closer than Boston—that meant going home. As he was reaching up his hand to ask when the field trip would be, his classmates were getting out of their seats. “Where’s everyone going?” he asked Will.
Will shook his head. Maybe Ephraim had some sort of attention deficit disorder, Will thought, and that’s why he was so dim. “To the Van de Graaff generator.”
“Right now? Don’t we need permission slips or anything?” Ephraim hadn’t packed a lunch, and he didn’t think he would have enough money on him to buy anything at the museum cafeteria.
“It’s not like it’s dangerous,” Will said, stuffing his notebook into his backpack.
Mallory walked by and said, “It’s here. In the school.”
“You have a Van de Graaff generator in the school?”
Mallory liked the way it was so easy to surprise Ephraim. He might have been the one from the city, but he sure was a bumpkin. “Sure. It’s right next to the planetarium. Will built it.”
Ephraim’s eyes grew even wider as he swiveled his head back toward Will. Will didn’t say anything. He had built it, it was true, but it was from a kit paid for from an alumni grant, and Ms. Little had helped him. At the time he’d thought that maybe his World’s Science Fair project would have something to do with electricity, but now he felt he needed to do something more ambitious.
The rest of the class had already gone ahead, leaving the three to follow behind. They didn’t walk together, though, but staggered themselves, each making sure not to get too close to the others.
The Van de Graaff generator was at the far end of the school. They went down a narrow set of stairs and then into a room that opened up several stories high. In the center were two large poles, each with a ball on top, the two balls pressed together. A pole with a smaller ball was in between them. At the base was a station with a control board, all surrounded by a metal cage. Will dropped his bag by the bleacher-style seats and went to the command center.
“Ephraim, why don’t you join your lab partner,” Ms. Little suggested.
Ephraim shook his head. “No, that’s okay.”
“Yeah, Ms. Little. I got it,” Will said, his eyes fixated on the control panel.
“I don’t know the first thing about Van de Graaff generators,” Ephraim said. That wasn’t entirely true. He had seen the show at the Museum of Science seventeen times. His favorite was the one he’d seen about Nikola Tesla. The presenter had pretended to be Tesla, and talked about how he was always in Thomas Edison’s shadow. Ephraim could relate to that.
“See. He doesn’t know anything about it,” Will agreed, and even though he was only saying what Ephraim had said, it still annoyed Ephraim.
“The best way to learn is by doing. Hop on up there, Ephraim.”
Ephraim, miffed and out to prove himself, did as he was told. He shut the door and locked himself into the cage with Will. The array of dials and buttons was dizzying. He tried not to get too close to anything.
“As I’m sure you all remember, a Van de Graaff generator is an electrostatic generator able to produce high voltages of electricity. We use it to study how electricity works. Why don’t we review how it functions just so we’re sure we’ve all got it before we start our experiment for the day?”
Everyone, Ephraim included, knew that Ms. Little was only reviewing for Ephraim’s benefit. Ephraim tried to listen carefully as Will explained.
Looking bored, Will pointed to the tower that held the two large spheres. “So there’s a rubber belt in there that goes around.”
“At sixty miles per hour!” Ms. Little interjected.
“Then there’s an adaptor there that sprays electricity onto the belt.”
Ephraim nodded, though he had no idea how electricity was sprayed.
“Then the belt brings it up and the spheres get a negative charge all around the outside. Then when you bring the neutral point close”—he pointed to the small ball on the pole—“it’s like the negative charges jump over to the neutral and you get the lightning bolt.”
“You got that?” Ms. Little asked. “It’s as if the negative charges are all bottled up and when that small ball comes close, it pops the cork, and out spills the lightning.”
Ephraim nodded. This all sounded vaguely familiar from his visits to the museum. His dad had told him it was just like when you got a static shock. The charge built up on you and then you touched another person or something metal and the electricity jumped. He and Price had spent whole afternoons rubbing their fleece sweatshirts and chasing each other around trying to zap one another. The Van de Graaff generator was like a really big version of that.
“So let’s see a few test trials before we get down to business,” Ms. Little said.
Will started fiddling with the dials and the machine purred into action. Ephraim had never been so close to the generator before. It loomed above him, and the vibrations seemed to go all around and through him.
Will pushed a button that raised the small ball a little higher. A lightning bolt jumped from the large spheres to the small one. Ephraim rocked back. Will snickered at him.
Ephraim set his jaw. “I just didn’t realize it was all warmed up and ready to go,” he explained.
“It’s ready,” Will said. He moved the ball on the pole around, and soon another bolt shot out. This time Ephraim managed to keep himself still, though his insides were quivering.
“Want to see something really cool?” Will asked.
“Sure,” Ephraim said, though he had serious doubts about what Will might think was really cool.
“Hold on,” Will said.
Slowly the cage started to rise.
“What are you doing?” Ephraim asked.
“We’re going to shock the cage.”
“What?”
“It’s completely safe. We’re in a metal cage; it’s just like being in a car.”
“Except we’re not in a car. We don’t have any rubber wheels.”
“That’s not actually what makes a car safe. Rubber is a good insulator, but it’s not that good.” He looked at Ephraim’s perplexed face. “Never mind. If this were dangerous, Ms. Little would be stopping me, wouldn’t she?”
Ephraim looked down at Ms. Little, who was smiling up at them. She probably thought that she had brought Will and Ephraim together. He turned toward his classmates, none of whom looked concerned. A little jealous, maybe, but not concerned.
The hum was getting louder and louder. It sounded an awful lot like the house.
“You’re sure this is safe?” Ephraim whispered.
Exasperated, Will said, “Yes. You could just reach right out and grab the lightning bolt if you wanted to.”
It sounded like a dare to Ephraim, a chance to prove he wasn’t a wimp—or an idiot. He reached out his hand.
Will turned just as Ephraim’s wrist passed through the bars of the cage. “Ephraim, no!”
The bolt jumped from the cage to Ephraim’s hand. Ephraim stumbled backward, slipped, and hit his head on the metal floor of the cage. The last thing he saw was Will’s face hovering above his own. “Ephraim? Ephraim? I didn’t mean it.” Then he closed his eyes.
Will knew that everyone thought he had shocked Ephraim on purpose. Probably even Ms. Little, who was Will’s favorite teacher. His dad would be proud of him. This gave him a sick feeling.
He weaved through the fallen leaves as he rode his bike home that afternoon.
Even if he had done it on purpose, like if there were some deep, dark part of him that actually wanted to hurt Ephraim, how would he have known that he’d fall down and hit his head? That’s what had knocked him out: not the shock but the fall.
The truth was he didn’t think anyone was stupid enough to actually reach out and try to touch a lightning bolt. It was Ephraim’s own fault for being just so plain dumb.
He rode over the leaves now, liking the noise they made when they crinkled under his bike’s tires.
No one else saw it that way, and he guessed he didn’t really either. It was his fault. It was that simple.
At the end of his driveway, he turned at their crooked and dented mailbox; the y in their name had turned upside down. People drove by and saw the mailbox, the broken-down cars and tractors, and shook their heads. Will pedaled hard and wondered if he would always be “that Wylie kid.”
