This STEM project is a favorite from our quarantine days of virtual programming.
Supplies:
Large jar (24 oz. spaghetti sauce jar or a large mason jar)
Water - 2 1/2 cups water (or until it reaches 3/4 of the way up the jar)
Oil - 1/2 cup
Sprinkle in as much salt as necessary but you'd need about 1/4 cup total
Food coloring (optional)
Directions:
Pour water 3/4 to the top of a mason jar. Stir in optional food coloring.
Pour oil into jar. Allow water and oil to separate.
Sprinkle salt into jar. Watch the reaction occur and make observations.
