Delhi’s pollution becomes a headache every winter. After Diwali, the air becomes so poisonous that breathing becomes difficult. To deal with this, Delhi government is going to create artificial rain through cloud seeding. This technology causes rain by adding chemicals to the clouds. The special thing is that there will be 8-10 chemical packets installed in the plane, which will be blasted by pressing a button. The special plane that reached Meerut from Kanpur on 23 October 2025 can show this magic in the next three days.
What is cloud seeding? Giving ‘seeds’ of rain to the clouds
Cloud seeding is a climate changing technique. In this, water droplets are added to moist clouds by adding chemicals, so that they become heavy and rain. This is different from normal rain, because here humans help. Delhi This is to clean pollution. The cost of the project is ₹3.21 crore, which is being jointly run by IIT Kanpur, IMD and Delhi Government.
How will 8-10 chemical packets be fitted in the plane? step by step
Delhi’s project is based on five modified Cessna aircraft. Each plane will fly for 90 minutes. The main method is…
1. Preparation
8 to 10 pockets or packets are installed under both the wings of the aircraft. These packets are filled with chemicals – mainly silver iodide, potassium iodide or dry ice (cold carbon dioxide). Sometimes salt is also used. These chemicals act as ‘seeds’ for water droplets.

2. flight
The plane flies among moist clouds. Focus on polluted areas of Delhi-NCR, like North-West Delhi. One flight will cover an area of 100 square kilometers. Altitude 3-5 kilometers.
3. Blast magic
The pilot presses the button. This causes the packets to explode – meaning the chemicals spread into clouds. Chemical particles stick to water droplets, which form larger droplets and rain. This process starts in 20-30 minutes. Rain will be light, but will wash away pollutants (like PM2.5).
pollution instant relief from
Clear air: Smoke, dust and toxic particles will be washed away by rain. Delhi’s AQI often reaches 300-400, which is dangerous. This can bring up to 100-200. Only polluted areas will be targeted. Without soaking the entire city. Countries like China, UAE have been doing this for years. China reduced pollution by 40% during the 2008 Olympics.
