World's Smallest Vacuum Cleaner Created by Indian Student
A college student from India, Tapala Nadamuni, has reclaimed his Guinness World Record by creating the world's smallest vacuum cleaner. At 23, he transformed a refillable ballpoint pen into a miniature vacuum, measuring just 0.25 inches (0.65 cm) along its shortest axis – smaller than the width of an average pinkie fingernail and 0.2 cm smaller than the previous 2022 record.
Nadamuni's innovative tiny vacuum operates through suction created by a small rotating fan powered by a four-volt vibration motor. It can effectively pick up dust particles, which can be easily emptied. His interest in inventing gadgets dates back to his childhood. Over the past two years, he invested about $238 (20,000 rupees) in regaining his record. This project included developing over 50 schematic diagrams and overcoming design challenges, such as ensuring adequate suction.
Previously, Nadamuni held a similar record in 2020 with a vacuum measuring 1.76 cm. Despite facing two rejections in his recent attempts, his perseverance paid off with his redesigned entry. His ingenuity impressed his peers and faculty alike, who praised the vacuum as the most beautiful creation they had seen.
For this record, a vacuum cleaner must be an electrically powered device that picks up debris through suction from a negative internal pressure, excluding the handle and power cord dimensions. Nadamuni's contraption meets these criteria, using bits of plastic, metal, and parts from a ballpoint pen to function effectively.
Nadamuni's accomplishment has garnered admiration and amazement from his college community, reinforcing his reputation as a talented inventor.
