UPI – A college student from India set a Guinness World Record by converting a refillable ballpoint pen into the world’s smallest vacuum cleaner.
Tapala Nadamuni, 23, spent about USD238 transforming his pen into a vacuum measuring just 0.25 inches at the shortest axis of its body.
He said his tiny vacuum creates suction via a tiny rotating fan powered by a four-volt vibration motor, and it picks up particles of dust that can then be emptied.
