This video showcases a mosquito coil — a spiral-shaped insect repellent commonly used in many countries.
The coil is made from powdered materials mixed with insect-repelling compounds. Once ignited, it burns slowly from the outer edge inward, releasing smoke that interferes with mosquitoes’ sensory systems and keeps them away.
The spiral design is efficient because it maximizes burn time while remaining compact. Despite being a very old invention, mosquito coils are still widely used due to their low cost and effectiveness.
