(PhysOrg.com) -- As with many of man's most basic ancient desires; to be able to fly, to become invisible etc. making it rain on command (or by prayer) has always been high on the list, and up to now, has proved more elusive than other advances in the sciences. Now however, physicists in Switzerland might have finally made a breakthrough. In their paper published in Nature Communications, they describe a method whereby a laser is used to create nitric acid particles in the air to which moisture will gravitate forming droplets.
