Shona has sent us a really interesting experiment to do with some household ingredients. It looks amazing! Do not attempt to drink it though or your tongue will turn blue and you’ll froth at the mouth, and likely be sick too! I love the way the colours move to the sides of the dish – its like magic, but actually its science!!!!
Here is Shona’s post:
Hi boys & girls, missing you all! Here is a little fun and easy science experiment for this afternoon- Magical milk.
What you will need…
Flat dish (I used a cake tin)
Milk
Food colouring
Fairy liquid
First pour some milk into the flat dish, pour a drop of each colour into the milk we used 3 colours. Then squirt some fairy liquid into the middle & watch the colours drift away to the edge of the bowl breaking the surface tension. Make sure you don’t look away as it happens very quickly!
We tried this again with 2 different colours (red & green) & at the end we added in 2 more colours (blue & orange) but put these at the Edge of the bowl this time rather than the middle. We squirted more fairy liquid in but this time swirled the dish around and watched the colours all come together and mix, it looked like the earth! Maybe you could create your own earth or why not try different colours to make another planet such as Jupiter, or Mars etc!

When liquid dish soap is added to milk with drops of food colouring on the surface, the soap reduces the surface tension of the milk and reacts with the fat. This interaction causes the fat particles in the milk to move and create swirls of colour.
