3、Unlike dry ice pellets, the particles of silver iodide do not evaporate when released.
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.
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.
4、Shooting for rain, meteorologist Huang Binming (right) and his crew launch canisters of silver iodide into the sky near Madoi.
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.
5、Aircrafts fly above and beside the storm clouds and drop tiny silver iodide crystals into them, triggering rainfall.
2、Clouds are sometimes seeded with silver iodide to induce precipitation.
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.
1、It was a compound called silver iodide.
