What you need:

A glass jar, a balloon, a bowl of ice water, a piece of string

What you do:

  • Blow up the balloon so that it is just a little too big to go into the jar.
  • Tie the end of the balloon with a piece of string so that the air cannot get out.
  • Now place the balloon in a bowl of ice water.
  • After some time take the balloon out and try to put it into the glass jar.

What you find:

The balloon goes inside the jar.

Why does this happen?

When you put the balloon in the cold water. the air in it gets cooled. The cooled air contracts and so the balloon diminishes in size and is able to go into the jar.

Can you change the colour of flowers! Here's how...

What you need: White flowers with long stems, like tuberoses, jasmine or zinnia, food colouring, water and a plastic container.

What you do:

1. Fill the plastic container with water and add some food colouring.

 2. Cut the ends of the stems of the flowers and put them in the coloured water.

 3. Check the next day.

What happens?

The petals would have tumed the colour that you added to the water!


 The plant draws up water from the soil through the roots and then up through the stem. As the water evaporates from the tiny pores in its leaves and flowers, the plant draws up more water. Since the flowers in the container didn't have roots, they sucked up the water through the stem.

 Try this!

Split the stem vertically down the middle and plant the halves in containers with water of two different colours. What happens?

 Fact of the matter

Plants draw up water from earth continuously. Cut flowers have to be put in water right away, otherwise an air bubble will form in the stem. Then the flowers will be unable to draw up any more water!

When you don’t clean the ceiling fan for some time, do the blades get uniformly dirty or do they get dirty in parts? Let’s find out.

What you do:

  • Ask your mom not to clean the ceiling fan in your room for two to three weeks
  • Observe the blades of the fan at the end of this period.

What you find:

That most of the dirt collects on the leading edges of the blades.

 Why does this happen?

Static electricity develops on the blades of the fan when they are in motion due to friction with the air The static electricity attracts dust particles. As the edges of the blades are the first to come into contact with the surrounding air, more dust collects on them than on the other parts of the blades.
