Indian college student creates world's smallest vacumn cleaner
Tapala Nadamuni, an innovative Indian college student, has crafted the world's smallest vacuum cleaner by ingeniously repurposing a ballpoint pen, earning him a new Guinness World Record. This remarkable invention measures just 0.25 inches at its shortest dimension.
Nadamuni invested approximately $238 to transform the pen into a fully functional vacuum cleaner. Utilizing a tiny rotating fan and a four-volt vibration motor, the device generates enough suction power to effectively capture fine dust particles.
According to Guinness World Records, this is not Nadamuni’s first record-breaking accomplishment. In 2020, he won the same category by creating a 0.69-inch vacuum cleaner. However, his record was soon surpassed by a device only 0.07 inches larger than his latest invention.
This time, Nadamuni revealed that he "came up with a completely new design," drafting over 50 detailed schematic diagrams to ensure his creation met the stringent requirements.
His latest invention has once again claimed the title, affirming his status as a trailblazer in the field of miniature engineering. "All the students in our college were amazed by this tiny vacuum cleaner, and my faculty told me it’s the most beautiful creation they’ve ever seen," Nadamuni proudly shared with Guinness World Records.
