Take your milk and get it warm pour in white vinegar stir until you start seeing chunks in the milk

Pour your milk and vinegar combination in a strainer get out all of the liquid so that all that is left is the chunks dry the chunks more with a paper towel

Once your milk and vinegar chunks are damp mold it into anything and place in container

Let the chunks dry for a while depending on how big your mold is the milk chunks will become hard as stone and the only way i could break mine was to hit it with a hammer
