A strange quiet filled the Cardboard Lab.

Clara, the eight-year-old Chief Engineer, stood in front of her new pride and joy—a giant, perfectly smooth, shiny whiteboard that her dad had helped her attach to the wall. With careful precision, she drew thousands of tiny dots 🎵 on it using a blue marker.

“According to my calculations…” she muttered, pushing her goggles up onto her forehead. “Air is very thin and light. It weighs almost nothing. I’ll prove it by drawing these floating particles. Total freedom, zero pressure. Pure gas theory.”

High up on a shelf, Copernicus the veiled chameleon blinked a lazy eye 🎵. Right now, he was the color of a bright blue sky.

Suddenly, a loud 🎵, rubbery stomping noise came from below: Smack! Shuffle! Smack!

The door burst open 🎵 and Leo tumbled inside. This time, his red cape was tied around his waist, and he wore pink swimming goggles on his head. He had taped small bathroom suction cups to his elbows and knees. In his right hand, he held a giant, brand-new and (luckily) clean toilet plunger with a bright red rubber cup.

Copernicus immediately puffed up 🎵 like a balloon and turned a warning shade of yellow 🎵.

“Base, this is Suction Cup Man!” Leo announced, striking a hero pose. “I’m starting my mission to walk on the ceiling!”

Clara sighed so heavily 🎵 that she almost blew her notes right off the table.

“Leo, you’re ignoring the basic laws of nature again,” she said. “Rubber isn’t sticky. You can’t walk on walls like a fly. Gravity will pull you right back down to the floor, and you’ll probably get a bruise.”

“Flies don’t have glue, they have super-paws!” Leo argued. “Watch this!”

Before Clara could protect her spotless new whiteboard, Leo swung the heavy plunger and smashed it against the wall with all his might—right in the middle of her drawing of gas particles.
