Ethan and Liam have been working with Mrs Maw on some really cool science experiments and today we were lucky enough to get to see one of these experiments. It is called 'The Great Milk Experiment' and it is something you can try at home with your family.
Instructions:
1. Place 0.5cm of milk in a shallow dish or saucer.
2. Add 2-3 drops of food colouring to the milk.
3. Add 1 drop of dish washing liquid.
4. Watch and see what happens!
Ethan and Liam showed us how to do this and they used three different drops of colours - red, blue and yellow, in different areas on the saucer. It was really interesting to see the colours all swirl together creating awesome patterns when the detergent was added. Mrs Maw told us if you get a part that doesn't do much, you can add another drop of detergent and it will make it go crazy!!!!
I wonder...
* What do you think is happening?
* How do the colours move?
* Do you think the same thing would happen if you used a different liquid?
