Watch: Create a Stone from Milk Leftovers

Steps of the experiment:

* Pour a cup of warm milk into a measuring cup (to avoid waste, you can use various milk leftovers).

* Add a teaspoon of white vinegar to the milk (available in large grocery chains, alongside citric acid and the like).

1. * Stir the mixture for about five minutes or until you see a 'chunky' substance forming called 'casein'.

* Take a strainer and strain the mixture to separate as much of the lumps from the liquids as possible. 

1. * Take the lumps left in the strainer, transfer them to a piece of paper towel, and dry them.

* After a few minutes, the mass will solidify into a material you can mold into different shapes.

1. * The next step is to let the shapes dry for about 48 hours on average, depending on the size of your creation. Once dried, you will have hard shapes like stone that you can paint and turn into a mobile or any other art creation.
