Cloud control: Giant lasers fired into the sky could be used to create rainfall

  • Technique could unlock the secrets of weather cycles
  • Humans could decide where and when it rains

Britons are notoriously obsessed with the weather, especially rainclouds.

Now, according to scientists, it seems they will soon be able to create their own washout conditions.

Using a powerful laser, researchers have created water droplets in the air.

The technique, called laser-assisted water condensation, could one day unlock the secrets of weather cycles and enable humans to decide where and when it rains.

While ‘cloud seeding’ has existed for some time it is not considered a safe way of creating rainclouds because it involves filling the atmosphere with small particles such as dry ice and silver iodide.

This means that while raindrops can form, chemicals are often spread far and wide and potentially damage the environment.
