Cloud Formation

Ever wondered how clouds are formed? Or where do they come from? Find out answers to your questions with the fun project provided below!

How are Clouds Formed?

A mass of ice crystals or water drops suspended in the atmosphere is known as a cloud. It is formed when the water condenses in the sky. The sky always possesses some amount of water vapours in it but it is invisible to us. Clouds are formed when an area of air becomes cooler until the water vapour there condenses to liquid form. At this point, the air is said to be saturated with water vapours. Below, we have provided an experiment to help you understand the formation of clouds better. You can try it yourself at home!

Cloud Formation Experiment


The main objective of this experiment is to focus on the formation of clouds by making use of a few household materials.


  • Droppers
  • Blue Food Colors
  • A clear Jar
  • Shaving Cream
  • A container of water


  • Take a small jar or a cup. Fill the water up to three-fourths of the way.
  • Add shaving cream at the top.
  • Wait until the shaving cream settles fully at the top of the water.
  • Now take a separate bowl, add few drops of food colouring (blood) along with a few drops of water.
  • Add it to a dropper or pipettes.
  • Now actual experiment begins.
  • Using these droppers just drop the colours on the cloud.


Now one could witness the cloud formation. Once the cloud is filled with water it would start to rain.

Clouds are nothing but masses of condensed water vapours and they show visible signs of atmospheric processes at work. Cloud’s regulate the energy balance of the earth by absorbing infrared radiations and scattering solar radiation. In addition to this, clouds redistribute surplus energy from the equator to the poles and return water to the oceans and land masses.

Practise This Question

A spring with no mass attached to it hangs from a rigid support.  A mass m is now hung on the lower end to the spring.  The mass is supported on a platform so that the spring remains relaxed.  The supporting platformis then suddenly removed and the mass begins to oscillate.  The lowest position of the mass during the oscillation is 5 cm below the place where it was resting on the platform.  What is the angular frequency of oscillation? Take g = 10 ms2
