The Texas summer was beginning to assert its oppressive authority. Even in the relative cool of the early mornings, the air in the shed was close and humid, making delicate soldering work a sweaty affair. Charlie's water monitoring project, codenamed "Aquasentinel" in his private notes, was hitting the inevitable snags that plagued any ambitious undertaking.
His primary nemesis was a persistent bug in the data logging software. Every few hours, the program would inexplicably crash, corrupting the most recent batch of sensor readings. He'd spent days poring over his QBasic code, his eyes gritty from staring at the flickering monochrome screen. His [Programming Logic Lv. 3] and [Debugging Lv. 2] skills were being tested to their limits.

Charlie grumbled internally at the System's unhelpful advice. He didn't need a break; he needed a breakthrough.
His mood wasn't improved by the fact that the town's water situation seemed to be worsening. The metallic taste was more pronounced, and there were rumors of another boil-water advisory looming. The urgency pressed down on him, a counterpoint to the stifling heat.
George Sr. poked his head into the shed one sweltering afternoon. He'd been surprisingly supportive, in his own gruff way, after Charlie had explained the project's aim. "Still wrangling them computer gremlins, son?" he asked, wiping sweat from his brow with a bandana.
Charlie just grunted, deleting another line of suspect code.
"You know," George said, leaning against the doorframe, "sometimes when the playbook ain't workin', you just gotta try a whole different formation. Somethin' unexpected." He recounted a story about a high school football game where a surprise onside kick in the final minutes had turned a losing game around.
Charlie only half-listened, but his father's words, "somethin' unexpected," echoed faintly in his mind. He was so focused on the software, on the intricate logic, that perhaps he was missing something more fundamental.
Later that day, Missy came in, her face streaked with dirt and concern. "Charlie, Mr. Henderson's geraniums are all droopy. He says the water's makin' 'em sad." Mr. Henderson was their elderly, kind-hearted neighbor, whose prize-winning geraniums were his pride and joy.
This was a tangible consequence, more immediate than abstract data points. Sad geraniums. It solidified Charlie's resolve.
He decided to take a break from the code and re-examine his hardware. He meticulously checked every connection, every solder joint. He even, grudgingly, took Paige's advice and scavenged some old optocouplers from a broken fax machine, carefully integrating them into his sensor input circuits. The signal did seem cleaner, but the software crashes persisted.
He was on the verge of throwing his keyboard across the shed when he heard a commotion outside. It was Sheldon, in a full-blown meltdown.
"It's illogical! Catastrophically inefficient! The coefficient of friction is clearly not optimized for this particular gravitational incline!"
Charlie sighed and went to investigate. Sheldon was standing by the driveway, where Georgie was attempting to ride a new, oversized skateboard down the slight slope, repeatedly wiping out.
"Georgie, your center of mass is too high," Sheldon lectured, "and your initial propulsion vector is misaligned with the optimal trajectory!"
"Shut up, Sheldon!" Georgie snapped, picking himself up and dusting off his jeans. "It's the stupid wheels! They stick!"
Charlie watched Georgie try again. The skateboard indeed seemed sluggish, its wheels not spinning freely. He knelt for a closer look. The bearings were cheap, unsealed, and probably full of grit.
"They need cleaning," Charlie said. "And better lubricant."
"Lubricant?" Georgie looked hopeful. "Like, rocket fuel?"
"No, Georgie. Like bearing grease. Or…" An idea, sparked by his father's "somethin' unexpected" comment and the current problem, began to form. He remembered seeing something in the garage, something Meemaw had bought last winter during a rare Texas ice scare.
He dashed to the garage, rummaged in a forgotten corner, and emerged triumphant, holding a spray can. "WD-40?" Georgie asked, skeptical. "That's for rusty hinges."
"It's a water displacer, degreaser, and light lubricant," Charlie corrected, already spraying a small amount into the skateboard's wheel bearings. He spun a wheel. It whirred freely, almost silently.
Georgie's eyes lit up. He hopped on the skateboard. It glided smoothly down the driveway. "Whoa! Awesome! You're a genius, little bro!" He then promptly lost his balance and crashed into Meemaw's prize-winning azaleas, but the skateboard itself had performed flawlessly.
Sheldon, however, was incensed. "You've introduced an uncontrolled variable! The experiment is compromised! WD-40's chemical composition could degrade the polyurethane of the wheels over time!"
Charlie ignored him. His mind was racing, not about skateboards, but about his crashing software. Water displacement. The shed was humid. Condensation. Could it be that simple? Tiny, almost invisible amounts of moisture forming on the exposed circuit board of his salvaged microcontroller, causing intermittent short circuits or data corruption, especially as the temperature fluctuated? The crashes often happened after the shed had heated up significantly.
It was a long shot, but it fit the pattern of intermittent, seemingly random failures.
He hurried back to the shed. He didn't have conformal coating to properly waterproof the board. But he did have a can of his mother's clear acrylic craft spray. Not ideal, but it might provide a temporary moisture barrier.
He carefully powered down his system, masked off the connectors, and gave the microcontroller board a light, even coat of the acrylic spray. He let it dry, the acrid smell filling the small space.
While he waited, he felt a presence. Paige was back, leaning against the shed doorframe, arms crossed. She'd clearly heard Sheldon's earlier tirade.
"Solving the world's transportation problems with household lubricants now, Cooper?" she asked, an amused glint in her eyes.
"Just helping Georgie defy gravity, and Sheldon's sense of order," Charlie said, trying to sound nonchalant. He was strangely nervous about her seeing his latest, rather desperate, troubleshooting attempt.
Paige's gaze fell on the can of acrylic spray. "Arts and crafts day?"
"Trying to protect the microcontroller from humidity," he admitted, feeling a bit foolish. "Thought condensation might be causing some of the glitches."
Paige walked over, peering at the now-drying circuit board. "Huh." She tapped the board gently. "It's a plausible theory. Those old chips are notoriously sensitive to environmental factors. We had a similar issue with a sensor array at a robotics camp once. Drove us crazy until someone figured out the morning dew was shorting a trace."
Charlie felt a small knot of tension ease. She wasn't mocking him. She understood.
"Did it work?" he asked. "For your sensor array?"
"Eventually," Paige said. "We ended up redesigning the enclosure with desiccants and a heated element. Overkill, but effective." She looked at his setup. "Your acrylic spray might do the trick for a while. Smart, if a little unorthodox."
A comfortable silence fell between them, a rare commodity. They stood side-by-side, two young scientists contemplating a shared enemy: the stubborn refusal of the physical world to always conform to elegant theory.
"So," Paige said finally, "still think you can fix Medford's water with this… homebrew setup?" There was less challenge in her voice now, more genuine curiosity.
"I think I can provide the data to help the people who can fix it," Charlie corrected. "If I can just get this damn thing to run stable for more than three hours."
He powered the system back on. The familiar green text scrolled across the screen. The sensors began transmitting their readings. pH: 7.8. Turbidity: 12 NTU. Temperature: 28°C. All within expected, if not ideal, ranges.
He and Paige watched the screen, the minutes ticking by. One hour. Two hours. The data kept logging, steady and consistent. No crashes.
A slow smile spread across Charlie's face. It was working. The unexpected deicer, or rather, its conceptual cousin, had helped debug his drought-related dilemma.

"Looks like your arts and crafts project paid off, Cooper," Paige said, a hint of admiration in her tone that made Charlie's chest feel strangely warm.
"Maybe," Charlie said, trying to sound modest, though he was practically buzzing with triumph. "Or maybe the computer gremlins just decided to take a coffee break."
Paige snorted, a small, surprisingly endearing sound. "Right. Well, I've got my own gremlins to wrestle. My greywater filter keeps getting clogged with lint from Mrs. Henderson's washing machine outflow."
"Lint," Charlie mused. "You need a pre-filter. Maybe a mesh screen with a backwash cycle?"
Paige frowned thoughtfully. "A backwash cycle… Not a bad idea, Cooper. Not bad at all." She gave him a final, appraising look. "Keep me posted on your water wizardry. It's… almost interesting."
She left, and Charlie found himself grinning at the empty doorway. The drought in his code seemed to be over. And Paige Swanson had just called his project "almost interesting." In their unique language, that was practically a standing ovation.
He still had to figure out deployment, but for the first time in days, Charlie felt a surge of optimism. The Aquasentinel was alive. And maybe, just maybe, it could actually help.
