A request from the Ministry of Defense to scientists: find a way to make it rain! The Pentagon donated $7.5 million to help achieve this goal and scientists believe they have found a way by using a high energy laser beam.

Static charged particles are what creates water activity and lightning in clouds and they believe the correct type of laser can create rain where and when you want it. Until now, a laser beam extends two meters in length but new filaments could extend that up to 50 meters with the possibility of extending hundreds of meters.

Scientists are confident using a laser is the best way to get the heavens to rain but so far no laser beam has been developed that can accomplish the task. Optical researchers at the University of Arizona and University of Central Florida are working on it but so far the filaments developed are not stable or long enough to reach the clouds. Once that is accomplished they believe the theory is solid.
