Fun science – changing a flowers colour

One of my favourite activities as a child was to pick my mothers flowers and try change their colour by leaving them in food colouring water.Tonight as I glanced over at the flowers I bought before lockdown I decided it was the perfect time to show Hamish this ” magic” trick.And so we grabbed some glasses, water, food colouring and 2 flowers and set our experiment up.Eager little hands were ready to help me and are still learning to do things slowly.As he poured the blue food colouring he managed to splosh it all over the counter. ( thank goodness for jick)So, when pouring the red, he was so much more gentle and deliberate.After we had coloured the water, he placed one flower in each glass and we have left them overnight.I cant wait to see his reaction in the morning.It takes 24 hours for the flowers to completely change colour and you normally use a plain white flower, so I’m not too certain how vibrant the shades will appear on our slightly greenish flowers.This morning our flowers had absorbed enough food colouring to change colour already.The longer we leave them the more vibrant the colour will appear.

How this works

Plants absorb water from the roots. This water travels up the stems into the flower petals.Although the cut flowers we use no longer have roots, they still absorb water up their stems through a process called capillary action.As the water is coloured with the food colouring, the dye enters the flowers petals and stains them to change colour.What is most interesting is that you need to leave each flower in dyed water to keep the colour as plain water would make the vibrant shades of the petals fade.

A list of easy STEM activities for families

STEM, stands for the study of Science, Technology, Engineering and Mathematics.

These 4 subjects teach critical thinking, logic and a large variety of other skills needed for when your child one day enters a future workplace.

But, how exactly do we as parents who grew up in a totally different world, equip our children for their future through everyday play ?

How do we prepare our children for their future ?

I’ve compiled a list of easy STEM activities that the entire family can enjoy together.


I have tried to separate the activities into a category each but many of the activities cross over into one or more of the other categories as well.
