Laser turns potentially be used to create rain. This was disclosed by Jerome Kasparian, a physicist from the University of Geneva. With these results, dry areas can expect more rain and scientists also got new techniques make it rain more effectively than the climate modification techniques.

In his research, Kasparian uses a laser to control the humidity. Scientists found that the laser can trigger the growth of raindrops on the humidity is lower, about 70 percent. "In the humidity, condensation does not occur in natural condition, where it takes 100 percent humidity," said Kasparian.
