• Cup
• Scotch
• Alcohol
• Water
• Scissors
• Kitchen paper towel

How to do it:

Step 1: Take a leaf and grind it to make a paste.

Step 2: Make a 1:1 solution of water and alcohol in a cup. Mix the paste from the leaves in the solution.

If you don’t have alcohol, you can use nail polish remover with a higher concentration in the solution.

Step 3. Cut a long strip of kitchen paper towel with scissors.

Step 4: Wrap the paper towel around the middle of the pencil so that one end of the kitchen paper towel hangs loose.

Step 5. Place the pencil on the cup so that the free end is immersed in the solution. Do not immerse the paper towel more than 3-4 cm.

Now leave the paper towel in place. After a few hours, you will notice different colored pigments on the strip of paper towel. This happens due to alcohol and capillary action.

Alcohol strips the leaves of color and dissolves them in the solution. On the other hand, capillary action is responsible for the liquid rising onto the paper towel.

You will also notice that after a while your paper will almost turn white due to the alcohol.

All in all, a simple but very educational experiment that you can do with your kids at home.

Participating in such activities helps children ask questions, think beyond the obvious, and observe. This is how learning should be!
