What You Need:
- White rose on a stem
- Different food colours - 5
- Glasses - 5
- Start your experiment in a place where your rose will be undisturbed for 12 hours.
- Split the rose stem into five strands, but make sure it does not break completely.
- Pour 200ml of water into each of the five glasses and stain each one with a different colour.
- Place each part of the fractured stem in a different glass.
- After 12 hours you will see that the rose has five different tints to it!
This experiment is a perfect example of capillary action. The ability of a liquid to flow against gravity and rise in a narrow space such as a tube is called capillary action.
