Answer 2

Answer:

Inspired by a vacuum cleaner, class 7 student Maanya Ramesh from Air Force School, Hebbal has solved the chalk dust pollution affecting teachers and students in classroom for ages. Her mini smart duster absorbs all the chalk dust while erasing the blackboard.

“When teachers erase the writing on the blackboard with a duster, the dust leave them coughing. Students sitting in the front benches are also affected. That was when I thought of doing something,” said Maanya, who exhibited her smart duster model at the Innovation Festival being held at Visvesvaraya Industrial and Technological Museum (VITM).

“My duster has an electric roller attached to it. It erases the blackboard faster even as the chalk dust is absorbed by the vacuum machine,” she said.
