“Little Miss Muffet Sat on her Tuffet Eating her Curds and Whey”
But what are curds? This experiment turns milk into a solid which sets hard when left to dry.
How to make Curds and Whey for Little Miss Muffet
Skimmed milk
White vinegar
Microwave-proof bowl or a pan and hob
Strainer/sieve
Instructions
- Add four teaspoons of white vinegar to one and a half cups of skimmed milk.
- Microwave the mixture for about a minute or heat on the hob/stove.
- After a minute, the milk and vinegar will separate into a liquid (the whey) and a solid (the curd).
- Strain the liquid and squeeze curds into one big lump. Squeeze out all the leftover liquid.
Remember to ask an adult to help.
- Allow the curds to cool and then mould into a shape.
- Leave the curd shape to harden. We call this plastic milk, but it’s not really plastic!
What are Curds and Whey?
The vinegar creates a chemical reaction which makes the milk separate into two parts, a solid (the curds) and a liquid (the whey.)The protein in the curds is what makes it act like rubber.

Very cool! My kids would like this!
Found you on abcand123learning’s Show & Tell.
Thanks for coming to take a look. Have a go, it is so easy!
what a fun experiment! i know my girls would find this interesting. thanks for sharing!
Thanks you. Let us know if you try it. x
We did something very similar to this in my 7th grade science class and to this day I can’t eat cottage cheese (it looked too much like it).
Ha ha! I hope we don’t put anyone else off! x
If you add enough vinegar, could you make something that won’t go off – i.e. could this be a new “type of playdough” could you make something with it? I have random thoughts, you don’t really have to answer that.
Thank you for joining Kids Get Crafty!

Hi. I love you site.
The Plastic milk that you have made is also known as paneer. Its a sort of cheese used in Indian cooking especially in the northern regions. We use lemon juice or vinegar to separate the milk. Its then, kept in a cheese cloth and hung, of which the whey drains out and the end product is allowed to become firm.
what chemical reaction occurs between milk and vinegar?
