First graders carried out a very easy and safe experiment. Steps:
1- Pour some milk onto a plate/bowl.
2- Add some drops of food colouring over the milk, right to the centre.
3- Dip a cotton bud into some liquid soap (dish soap).
4- Place the cotton bud with the drop of soap directly onto the food colouring and watch the colourful fireworks!
The milk fat interacts with the soap, which causes the milk to go wild!
