English Poorvi Class 7 My Brother’s Great Invention Notes

Introduction

“My Brother’s Great Invention” by Anita Rau Badami is a humorous and engaging story about a young boy named Anand, who fancies himself a scientist and creates quirky inventions that often lead to chaos. Narrated by his older sister, Anita, the story explores themes of creativity, imagination, perseverance, and the challenges of pursuing innovative ideas. The narrative is set in a household where Anand’s experiments, such as a faulty burglar alarm and a mysterious time machine, cause both trouble and unexpected outcomes, particularly during a burglary incident.

Summary of the Story

The story begins with Anita introducing herself (14 years old) and her younger brother Anand (13 years old), who loves tinkering with electrical gadgets, believing he is a scientist. His latest invention, a burglar alarm, goes awry when it soaks their father with water, angering him. Inspired by a recent wave of thefts in their colony, Anand designs the alarm to detect thieves by triggering a clanging sound and dropping a water bag. However, it mistakenly targets their father, who opens the door gently, revealing the invention’s flaw.

Anand’s next project is a time machine, inspired by the film Back to the Future. Despite his parents’ skepticism and attempts to curb his tinkering (locking his toolbox and monitoring appliances), Anand transforms his room into a workshop filled with wires, levers, and bulbs. His parents forbid him from testing the machine until they return from a trip to Kharagpur.

While their parents are away, Anita hears strange noises at night and wakes Anand, suspecting a burglar. They discover Boppa, a local sweeper and apparent thief, breaking into their house. Anand cleverly misleads Boppa into entering his room, where the time machine is located. Strange noises (crashes, thumps, and humming) follow, and Boppa mysteriously disappears, leaving only his green scarf. Neighbors, alerted by the children’s shouts, arrive but find no trace of Boppa. Anand insists his time machine transported Boppa to the past, though others dismiss it as imagination. The machine is later dismantled by their father, who deems it unsafe. Anand, undeterred, begins a new project to contact extraterrestrial creatures.
