덜컹대는 물주기 기계

The Big Idea

My family left for a whole week at the lake, and my big job was to stay home. I have always loved a tricky puzzle. The garden needed water every single day, or the young beans would droop. I did not want to carry heavy buckets across the yard each morning. So I decided to build a machine that could water the plants for me. I gathered cardboard, string, tape, and an old plastic bottle from the recycling bin. My notebook soon filled up with arrows, funnels, and hopeful little drawings.

The First Try

My first machine used a long cardboard ramp to guide water toward the plants. I poured water into the top, and it rushed down far too fast. The soggy cardboard bent, collapsed, and dumped the whole puddle on my shoes. Cold water splashed everywhere. I stared at the mess, feeling a little silly but also strangely curious. Cardboard alone was simply too weak to hold that much heavy water.
