If anyone ever wondered how different two brothers could be, they could come look at Nachi and Yudi for their answer

Yudi leaned over the mixture on his desk. Was it his imagination, or were there bubbles starting to form on the surface? How long had it been anyway? The stopwatch in his hand read three minutes, thirty-one seconds to go, so according to the book — he spun around and checked the book splayed out on his bed — it should’ve been showing a “frothy layer of bubbles” already.

Why did science have to be so... non-scientific?

Yudi sighed. He bent over the Pyrex dish again, prodded the mixture. There, something was starting to happen… or maybe not.

“Yuuuudi,” he heard, and someone started opening the door to his room.

“Don’t come in!” he yelped. “There’s something on the floor!”

The Pyrex dish was left to its own devices as Yudi skidded across the bedroom. An assortment of tools, wires, and plastic tubes were arranged in methodical piles right in the line of danger. He scooped them up and deposited them carefully on the bed, behind the book. This room was too small for a budding scientist.

“Can I come in now?” his older brother Nachi asked, sounding annoyed. “Whatcha doing in here, anyway? More experiments?” He wrinkled his nose. “Don’t you get enough of that in school?”

“I like it,” Yudi mumbled, but he could feel his face turning red. Nachi was a basketball star, happiest while he was playing sports, and hated anything related to school or books. And Nachi thought he, Yudi, was a total nerd for choosing reading, stargazing, and scientific experimenting as his favorite hobbies.
