1、It was a compound called silver iodide.
2、Clouds are sometimes seeded with silver iodide to induce precipitation.
3、Unlike dry ice pellets, the particles of silver iodide do not evaporate when released.
4、Shooting for rain, meteorologist Huang Binming (right) and his crew launch canisters of silver iodide into the sky near Madoi.
5、Aircrafts fly above and beside the storm clouds and drop tiny silver iodide crystals into them, triggering rainfall.
6、Desperate people have tried everything from firing cannons into the sky to lacing clouds with silver iodide. Now researchers have attempted to make it rain with lasers.
7、Cloud-seeding is a technique to enhance rainfall by introducing particles - often silver iodide crystals - into cloud systems, to help condense water vapor into raindrops.
8、For decades, MayDay parades in Moscow have taken place under clear blue skies, aircraft having deposited dry ice, silver iodide and cement powder to disperse clouds.
9、The chemicals fired into the sky, usually dry ice or silver iodide, are supposed to provide a surface for water vapour to form liquid rain.
