- Fill the tall cup with the milk and microwave for 2 minutes
- Add 4 tablespoons of vinegar and stir until rubbery clumps form in the milk
- Leave to cool
- Over a bowl, pour the mixture through a strainer, take out the rubbery bits and wash them under running water
- You now have your own plastic that you can shape and mould!
- Leave it to dry on a paper towel and then you can paint it.
Warning: The milk will be hot straight out of the microwave, so wear some oven gloves, or even better, ask an adult to help you!
