Who narrates 'My Brother's Great Invention'?

The story in short

Unit 3 of Poorvi celebrates imagination, invention and the wonder of discovery. The opening prose, 'My Brother's Great Invention', is narrated by fourteen-year-old Anita, whose younger brother Anand is a self-styled inventor forever building gadgets. One of his contraptions, a 'burglar alarm', misfires and drenches their father, sparking a family uproar; later Anand shuts himself away to build what he calls a time machine. When a real intruder breaks in one night and mysteriously vanishes near the device, Anand is convinced his machine sent the burglar into the past, leaving the question playfully unresolved. The unit's poem, 'Paper Boats' by Rabindranath Tagore, captures a child's imagination as he floats paper boats down a stream, writing his name and village on each, loading them with dawn flowers, and dreaming that fairies of sleep sail them under the midnight stars. The third reading, 'North, South, East, West' by C.G. Salamander, is a travel diary of dated letters in which a curious girl named Shaana journeys across India with her parents, marvelling at deserts, lakes, beaches and the mangrove wetlands of the Sundarbans while noticing worrying signs of climate change. Together the readings honour childhood curiosity, the inventive spirit, and the dreams that drive both science and exploration.

The story in 6 beats

  2. 2After watching a film on time travel, Anand builds a time machine and keeps everyone disturbed and worried.
  3. 3Papa refuses to test the machine, and Ma makes Anand promise not to touch it while the parents are away.
  4. 4At night, Anita hears noises, wakes Anand, and the thief Boppa breaks into the house and locks them inside.
  5. 5Anand sends Boppa into his own room, where a crash and strange sounds begin after the time machine starts.
  6. 6Neighbours rescue the children, but Boppa vanishes, leaving only his green scarf near the humming machine.
