REMEMBER THAT IT'S IMPORTANT TO ALWAYS WORK UNDER ADULT SUPERVISION. SOMETIMES WE USE THINGS THAT CAN BE HARMFUL, LIKE SCISSORS, SO DON'T EVER ATTEMPT TO MAKE THESE CRAFT PROJECTS ALONE.

1. Measure out 4 ounces of milk into a measuring cup. Pour it into a small pan and with an adult helper, heat the pan over a stove to bring the milk to a boil. As the milk comes to a boil, it should curdle. This should take roughly ten minutes. Be sure to stir it around from time to time to keep it from burning into the bottom of the pan.
2. Once your milk has curdled into a semi-solid lump, pour out any liquid excess onto a paper towel.
3. Transfer the remaining lump in the pan into a small jar.
4. Add one teaspoon of vinegar to the jar with the lumpy milk.
5. Shake up the vinegar in the jar a bit to make sure it covers the milk. Put the lid on the jar and let it sit for about an hour.
6. After an hour, the vinegar should be soaked up into the milk lump. Pour the lump out onto a paper towel. Now you can mold the milk into different shapes. Mold and play with it however you’d like.
7. Once you’ve molded the milk into a shape you like, place it on the paper towel and let it dry for a few hours.
