You will need:
2 white colour flowers
2 glasses of water
Any 2 food colours
(preferably a darker
colour, like blue and red
None of us can see water go all the way from the soil into a plant. But what if there was a way to show you that the plants actually suck up water? Follow this simple experiment and you will know.
INSTRUCTIONS
- Take water in a glass, and pop a few drops of
blue food colour to the water. Mix well. - Take the other glass and add a few drops of red food colour to it.
- Place a flower in each glass and leave it aside for a while.
- In case your flower has been cut a while ago, you may want to trim the base a little bit and then place it in the water.
- This is because the stem of a flower that has been cut a while ago will start to ‘heal’ and thus absorb less water.
- So, after you have placed your freshly trimmed flowers in the glasses of water all you have to do is wait and wait for some more time.
- After a long wait, you will notice that the flowers have taken the colours of the liquids in which they were kept.
RESULT
Flowers change colours depending on the water they were kept in. The capillary action of the flowers helps them to absorb water through their stem. We can never see this; but thanks to the drops of colour that we added to the water, we can see clearly that the flowers do indeed absorb water.
