Indian student sets Guinness World Record by creating tiniest vacuum cleaner using ballpoint pen
Nadamuni set the previous record in 2020 with a 1.76-cm vacuum. Over the last two years, he has made two unsuccessful efforts to reclaim the title.
Tapala Nadamuni, a 23-year-old Indian student created the world’s tiniest vacuum cleaner out of a pen, earning him a spot in the prized Guinness World Records.
“Measuring just 0.65 cm (0.25 in) – less than the width of an average pinkie fingernail – it is 0.2 cm smaller than the previous record set in 2022,” Guinness stated in a report released on September 3.
“The vacuum is measured by the shortest axis of its body, meaning the handle and power cord dimensions are excluded from the final measurement,” the report stated.
According to Guinness, Nadamuni set the previous record in 2020 with a 1.76-cm vacuum. Over the last two years, he has made two unsuccessful efforts to reclaim the title.
This time, he said, he “came with a completely new design,” creating more than 50 schematic designs to make sure his work complied with the specifications.
A vacuum cleaner is an electrically operated apparatus that uses suction caused by a negative internal pressure to collect dirt.
Functionality and Challenges
Nadamuni’s vacuum cleaner is primarily built of a refillable ballpoint pen, with the addition of small pieces of plastic and metal. Inside the hoover, a tiny rotating fan powered by a four-volt vibration motor generates suction.
When connected to a power source, the vacuum cleaner emits a whirring sound and can suck up dust particles that can be emptied later.
Achieving appropriate suction was difficult for Nadamuni, and the 23-year-old student revised his design after overcoming obstacles during initial testing.
