Around the world, many places are suffering from drought, and people have no other way  Today, some scientists discovered a laser  When launched, it creates water droplets in the air, causing clouds to add moisture and bring rain
They believe it will help people determine rainfall and timing and replace traditional methods of artificial rainfall
The study found that the effects of different wavelengths of laser light on the clouds were inconsistent, and that the traditional method was easier to operate than the laser rain method.
