An Indian college student, Tapala Nadamuni, set a Guinness World Record by converting a refillable ballpoint pen intothe world`s smallest vacuum cleaner.

His vacuum, measuring just 0.25 inches at its smallest axis, was created with a $238 investment. It operates with a tiny rotating fan powered by a fourvolt vibration motor to suction dust particles, which can then be emptied.

Nadamuni, who previously held the record in 2020 with a 0.69-inch vacuum, surpassed a device measuring 0.07 inches more than his latest creation. He shared that his college community was astonished by the tiny vacuum, calling it the `most beautiful creation` they`ve seen.
