A 23-year-old student from India named Tapala Nadamuni has set a new Guinness World Record by creating the world’s smallest vacuum cleaner.

Nadamuni transformed a refillable ballpoint pen into a tiny vacuum that measures just 6 millimetres at its shortest axis. He spent about $238 to build the unique device.

The vacuum works using a small rotating fan powered by a four-volt vibration motor, which creates suction to pick up dust particles that can be emptied later. Nadamuni previously held the same record in 2020 with a vacuum measuring 8 millimetres, but his record was later broken by another device.

His classmates and teachers were impressed by his invention, calling it a beautiful creation. Nadamuni hopes his achievement will inspire other students to think creatively and work on innovative projects.

On the final morning of camp, the weather changed quickly. Dark clouds gathered over the hills, and a chilly wind moved across the field. The teacher checked the forecast again and decided the group should pack up the tents earlier than planned. Some students were disappointed, but others were relieved because the ground had already become damp. The report on the radio described the afternoon as unsettled, with showers possible and low temperatures expected. Although the camp finished sooner than hoped, the students agreed that it was better to leave before the weather became worse.
