Showers of Blessing

That feeling after drinking a glass of ice cold water on a hot day doesn’t just hit the spot but it also keeps you alive and allows your body to function regularly. With 70% of our body is made up of water, ensuring that one is hydrated all the time is important, especially in hot and humid countries. This fact is further emphasized by how a man can survive three weeks without food but only three days without water.

Much like us, plants need water to survive as well. But who gives them a drink? How do plants and crops which can grow in an area as big as twenty football fields acquire water without really moving? The answer to that is that it comes to them. 

When the sun warms up the waters from the lowliest puddles by the roadsides to the massive rivers, lakes, and oceans; it turns the water; which is in liquid form, into water vapor that rises into the air. That water vapour then forms clouds, which contain small drops of water or ice crystals. The clouds are formed way up in the sky which can stretch be as high as three thousand meters (which is the distance between KLCC and KL Tower) up to eighteen thousand meters.

As clouds rise higher and higher, the air gets colder and colder. This causes the water vapor to condense into liquid form. When the water in the cloud becomes too heavy, gravity causes it to fall back to the ground as rain or snow. This entire process is known as precipitation. Rain is important to keep our farmlands, jungles, and flora healthy and It also cleans the air of dust and keeps the air cool.

See how precipitation forms.

funnel, plastic bag, glass jar or container, hot and cold water, ice cubes.

1. Pour one cup of hot water into the jar or container.
2. Place the funnel in the jar or container and make sure the contact point between the rim of the jar and the funnel is airtight. You can use tape or Plasticine for this.
3. Put the plastic bag into the funnel.
4. Pour the cold water into the plastic bag and add the ice cubes.

5. Observe what is happening in the jar.

The world’s water cycle is never ending. It travels on a journey from the sky to the land or sea and travels back up to the clouds again!
