Alchemists in the past were fascinated by making new substances just like chemists are today. Here is a simple experiment in which you can make a plastic from milk and vinegar. Follow the steps and record your observation as you go along.
1- Measure out 300 ml of milk into a beaker or a measuring cup and warm it carefully. The milk should not get so hot that it boils.
2-Add 15 ml of vinegar to the milk and stir the two liquids together.
Step 3:3-Leave the mixture to cool for 15 minutes.
4-Place a kitchen sieve or filter paper over a second beaker and pour the mixture into the sieve.
Step 5:5-Squeeze any solid substance in the sieve or the filter paper to remove more liquid.
6-Tip the solid in the sieve or the filter paper onto a paper towel.
