The three things needed to make a cloud are:

  • Water Particles
  • Lifting and cooling
  • Condensation Nuclei

The water molecules need something to collect on to create raindrops so comes in the "dust particles" or Condensation Nuclei (it does not have to be dust just something for the water molecules to collect on). The lifting and cooling pushes the drops up and down in the newly formed cloud and then when the drops get too heavy for the air to hold them up they fall.
