Look out, Weezy and Fat Joe—you aren’t the only ones making it rain.
ABC reports—scientists from Germany and Switzerland have found a way to create raindrops with a laser beam.
New Scientist sheds some light on the process.
“A cloud chamber was filled with air that was saturated with water. Short pulses of infrared laser light were then fired into it. This ionized the air and triggered water droplets to condense and form a cloud.”
Wait—water...from light? How does that work? Nature.com explains...
“...laser filaments can induce water condensation and droplet growth up to several [micrometers] in diameter in the atmosphere as soon as the relative humidity exceeds 70%.”
So, basically in order for it to work-- there already has to be water in the atmosphere.
International Business Times tells us the scientists behind this experiment want to control the weather to help fight floods and end drought.
But all rap puns aside-- isn’t there already a way to make it rain?
Technabob explains—traditionally, a method called “cloud seeding” has been used to create rain by injecting a certain chemical like silver iodide into the air. The problem is—the chemicals are toxic.

So when will scientists take this experiment to the skies? One researcher tells Fox News- hold on to your umbrellas-- it’s gonna be awhile.
“…[the watery particles are] currently limited to a few microns…They should be 10 to 100 times larger to produce actual rain.”
But once the raindrops reach the right size—scientists say it’ll be a cinch to shoot the light from the ground and into the atmosphere.
