Tapala Nadamuni, a 23-year-old student from India, has set a new Guinness World Record for the world's smallest vacuum cleaner, measuring just 0.65 cm—smaller than a pinkie nail and 0.2 cm smaller than the previous record. Nadamuni, who previously held this title in 2020, spent two years refining his design after facing two unsuccessful attempts. The innovative vacuum is primarily made from a refillable ballpoint pen, with additional plastic and metal components, and features a tiny rotating fan powered by a four-volt vibration motor to create suction. Despite initial challenges in achieving adequate suction, his persistence led to a successful design that effectively collects dust. The record was officially announced by Guinness World Records, which states that the vacuum's size is determined by the shortest axis of its body, excluding the handle and power cord. Nadamuni expressed his excitement over reclaiming the title, showcasing his passion for inventing gadgets.
