Firing Laser Beams Could Make It Rain, Study Says

While man's attempts to manipulate the weather can be traced throughout history, now scientists at the University of Geneva have successfully tested out a rainmaking technique triggered by shooting laser beams into the sky, reports The Guardian.

Published in Nature Communications Journal, the experiment entailed firing laser beams into the air, which formed nitric acid molecules and drew condensation for water molecules, according to The Telegraph.

The researchers spent 113 hours shooting laser beams across Switzerland's Rhône river. Though the experiment didn't bring about water drops big enough to qualify as actual rain, Wired reports the effects of the lasers were substantial enough for scientists to continue further work on laser-assisted water condensation.

Jérôme Kasparian, a physicist at the University of Geneva who led the study, told Fox News, "We are still far from laser-induced rainmaking." Though the lasers brought about condensation and water particles the size of a few microns, according to Kasparian, "They should be 10 to 100 times larger to produce actual rain."
