The Great Seed Sifter

Maya loved solving problems, especially when the solutions required spare nuts, bolts, and a bit of imagination. Her family's garage was not a place for parking cars; it was an inventor’s workshop. Metal shelves held jars of rusty screws, spools of copper wire, and discarded bicycle parts. Maya spent every Saturday morning at her workbench, sketching blueprints in a blue spiral notebook.

Her latest challenge came from her neighborhood's community garden. During the autumn harvest, gardeners had collected thousands of seeds from sunflowers, sweet peas, and tiny radishes. Unfortunately, a sudden gust of wind had tipped over the storage boxes, mixing all the seeds together in a single enormous bucket. Sorting them by hand would take weeks of tedious picking.

"Every difficult chore is just an invention waiting to happen," Maya declared to her younger brother, Julian, who was spinning a discarded roller skate wheel on the concrete floor.

Maya sketched three different designs before choosing the best concept: a multi-tiered mechanical sifter. She would build an inclined wooden chute fitted with wire mesh screens. The top screen would have wide gaps to let small and medium seeds drop through while catching large sunflower seeds. A second, tighter screen would catch sweet pea seeds, allowing only powdery dirt and miniature radish seeds to reach the bottom tray.
