The gymnasium of Medford Elementary School buzzed with a nervous energy that was palpable, a chaotic symphony of excited chatter, last-minute adjustments, and the faint, tell-tale scent of baking soda and vinegar. Tri-fold poster boards stood like proud, colorful monoliths on rows of folding tables, proclaiming hypotheses, methodologies, and conclusions with varying degrees of scientific rigor. It was Science Fair Day.
Charlie, flanked by Missy who served as his enthusiastic if somewhat distracting pit crew, carefully set up his project: the Humane Automated Pest Redirection System. The H.A.P.R.S. unit itself was a compact, neatly assembled device housed in a weatherproof plastic casing (salvaged from a broken Tupperware container, much to Mary's initial chagrin before Charlie assured her it was "for science"). A small solar panel, procured from a disassembled garden light, was mounted on top, charging a small lithium-ion battery. The motion sensor and the tiny, adjustable water nozzle were discreetly integrated. His poster board was a model of clarity and conciseness, with neat diagrams, flowcharts explaining his simple algorithm, and even a small section on "Observed Squirrel Behavior and Iterative Design Improvements."

Missy, wearing a laminated badge Charlie had made for her that read "H.A.P.R.S. Chief Operational Support," hovered protectively. "Okay, Charlie, everything looks super-duper! If any squirrels try to mess with it before the judging, I'll… I'll redirect them!" she declared, brandishing a plastic ruler like a tiny, determined knight.
A few tables down, Sheldon was holding court, his project an even more bewildering entanglement of yarn, Slinkys, and blinking LEDs than it had been in the garage. He was attempting to explain the concept of Calabi-Yau manifolds to a deeply confused-looking Principal Peterson and a nodding, but clearly uncomprehending, Mrs. Davis. "…and thus, you see, the compactification of these extra spatial dimensions, while not directly observable, is crucial for the vibrational consistency of the superstrings, represented here by the variegated chenille pipe cleaners…" Principal Peterson blinked slowly, a man clearly wishing he were anywhere else.
Charlie scanned the gymnasium. And there she was. Paige Swanson. Her project, "Aerodynamic Optimization for Enhanced Lift and Reduced Drag in Micro-Air Vehicle (MAV) Applications," was, as expected, impressive. Her display featured several sleek, 3D-printed drone prototypes (where had she gotten access to a high-resolution 3D printer? Charlie made a mental note to investigate), detailed graphs of computational fluid dynamics simulations, and even a small, enclosed wind tunnel – a significant upgrade from her "homemade" version – through which she was demonstrating the airflow over her custom airfoils using colored smoke. A small crowd had already gathered, impressed by the professional sheen of her presentation.
Paige caught his eye and gave a curt, challenging nod. Charlie returned it. The gauntlet was thrown.
The judging began. Teams of teachers, a few local engineers, and, to Charlie's mild surprise, Dr. John Sturgis, Sheldon's university physics professor, moved slowly through the aisles, clipboards in hand. Dr. Sturgis, looking slightly out of place amongst the elementary school chaos but gamely sporting a "Science Judge" ribbon, paused for a long time at Sheldon's display, engaging him in a rapid-fire exchange that left everyone else in the vicinity looking dazed.
When the judges approached Charlie's table, he took a calming breath. Mrs. Higgins, his third-grade teacher, smiled encouragingly. Mr. Henderson, an engineer from Texas Instruments, peered at the H.A.P.R.S. unit with a critical eye.
"So, young man," Mr. Henderson began, "explain your project."
Charlie launched into his prepared explanation, keeping his language clear and avoiding overly technical jargon. He explained the problem – unwanted pests at bird feeders – his hypothesis that a targeted, humane deterrent would be effective, and the design of his system. He demonstrated how the motion sensor triggered a brief, precise pulse of water from the nozzle.
"And it's solar-powered?" Mrs. Higgins asked, impressed.
"Yes, ma'am," Charlie confirmed. "To ensure autonomous, off-grid operation and minimize environmental impact." He'd even calculated the optimal angle for the solar panel for Medford's latitude.
Mr. Henderson was examining the internal wiring, visible through a small access panel Charlie had included. "Neat soldering work, son. Did you design the control circuit yourself?"
"Yes, sir. It's a simple logic circuit based around a salvaged microcontroller, programmed with a basic conditional algorithm."
Just then, Dr. Sturgis arrived, having finally extricated himself from Sheldon's lecture on M-theory. He looked at Charlie's project, then at Charlie, a flicker of recognition in his eyes. He'd seen Charlie a few times with Sheldon at the university.
"Charles, isn't it?" Dr. Sturgis said, his voice gentle. "Sheldon's brother. This is… remarkably practical. And ingeniously simple. The application of a targeted kinetic deterrent… fascinating." He peered closer. "Is that an ATtiny85 microcontroller you've repurposed there?"
Charlie was momentarily surprised Dr. Sturgis recognized the specific chip. "Yes, sir. From an older toy."
Dr. Sturgis chuckled. "Resourceful. I like it." He made a note on his clipboard.
As the judges moved on towards Paige's display, a minor commotion erupted nearby. Billy Peterson, whose project was a rather uninspired "Does Brand X Paper Towel Absorb More Water Than Brand Y?" (spoiler: it did, marginally), had apparently tripped over a power cord connected to a neighboring project – a potato-powered clock that was now decidedly unpowered. The clock's creator, a tearful second-grader, was on the verge of a meltdown.
In the ensuing mild chaos of teachers rushing over and Billy protesting his innocence, a shadowy figure – an older, surly-looking sixth-grader named Butch Donovan, known for his bullying tactics and a general disdain for anyone smarter than him (which was most people) – sidled past Charlie's table. With a swift, almost imperceptible movement, Butch "accidentally" knocked a half-full cup of fruit punch, left carelessly on an adjacent table, directly onto Charlie's poster board.
"Oops, my bad," Butch sneered, not sounding sorry at all, before swaggering off.
The sticky red liquid cascaded down Charlie's carefully lettered diagrams and graphs. Missy gasped in horror. "Charlie! Your beautiful board! That big meanie!"
Charlie felt a surge of frustration, quickly suppressed. Panicking wouldn't help. The poster board was likely ruined, but the H.A.P.R.S. unit itself was untouched, its weatherproof casing doing its job.
[System Advisory: External Sabotage Detected. Emotional Regulation Protocols Engaged. Optimal Response: Damage Control and Mitigation.]
Before Charlie could react further, Paige Swanson was there. She'd seen the whole thing. She had a pack of industrial-grade wipes in her hand – likely for cleaning her own pristine setup. Without a word, she started dabbing at the worst of the punch spill on Charlie's board.
"Donovan's a troglodyte," she muttered, her expression grim. "Can't stand anyone having more than two brain cells to rub together."
Charlie was surprised by her intervention. "Thanks," he said, genuinely. He took some wipes and joined her, trying to salvage what he could. The ink was smearing, but perhaps some of it could be saved.
"Your device is still functional, right?" Paige asked, nodding towards the H.A.P.R.S. unit.
"It should be. The casing is sealed."
"Good. The board is just for show. The tech is what matters." She gave him a sharp look. "Don't let that idiot get to you, Cooper. Your water-squirter is… surprisingly not terrible."
Coming from Paige, that was high praise.
The judges eventually returned for a final look-around before deliberating. They noted the damaged poster board. Charlie briefly, factually explained what happened, without embellishment or accusation. Mr. Henderson frowned in Butch Donovan's direction, making a mental note.
Finally, it was time for the awards. Various categories were announced: "Most Creative," "Best Environmental Focus," "Most Likely to Cause an Explosion (Honorable Mention)" – which, to no one's surprise, went to a fifth-grader who'd managed to create a small but impressive plume of purple smoke.
Sheldon received a "Special Commendation for Theoretical Ambition," which he accepted with a speech about the importance of funding blue-sky research, much to the bewilderment of the assembled students and parents. He was clearly disappointed not to have won the grand prize, later lamenting to Mary, "Mother, their inability to grasp the fundamental tenets of quantum gravity is a tragic indictment of the local educational system!"
Then came the overall winners.
"In third place," Principal Peterson announced, "for her innovative approach to household chemistry, Suzie Mayweather for 'The Rainbow Volcano!'"
"In second place," he continued, a smile playing on his lips, "for an impressive display of aerodynamic engineering and future-forward thinking, Paige Swanson with 'Aerodynamic Optimization for MAVs!'"
Paige accepted her ribbon with a polite, professional nod, though Charlie caught a flicker of disappointment in her eyes. She was clearly aiming for first.
"And the Grand Prize winner of this year's Medford Elementary Science Fair," Principal Peterson boomed, "for a project that is practical, ingenious, and demonstrates a clear understanding of problem-solving and sustainable design… Charlie Cooper with the 'Humane Automated Pest Redirection System!'"
A wave of applause went through the gymnasium. Missy shrieked with delight, jumping up and down and hugging Charlie fiercely. "You won, Charlie! You won! Your squirrel-squirter is the best!"
Charlie felt a strange mix of elation and surprise. He hadn't expected to win, especially after the poster board incident. He walked up to receive his oversized blue ribbon and a gift certificate to a local electronics store (which his mind immediately began allocating towards advanced microcontroller components).
Dr. Sturgis winked at him. Mr. Henderson gave him a thumbs-up. Even Paige offered a small, almost imperceptible nod of acknowledgment, which Charlie interpreted as "Okay, Cooper, you got lucky this time. But I'll get you next year."
The rivalry, it seemed, was well and truly on.
As they packed up, Missy chattered excitedly about how they would celebrate. Charlie, however, was already thinking ahead. The prize money was a start. His H.A.P.R.S. design was proven, at least in concept. Perhaps… perhaps this was more than just a science fair project. Perhaps this was the first step towards something bigger. The sparks of innovation had been fanned, the minor sabotage overcome, and even Sheldon's lament couldn't dampen the quiet satisfaction of a problem solved, and a victory earned. The showdown was over, but for Charlie Cooper, the real work was just beginning
