15、soon as you take the pressure off, it becomes a liquid again.

17、talk to you about the positive and negative charges of molecules. We can demonstrate how these interact through a simple experiment using milk, dish soap, and food coloring.

18、er of the milk. They should form one large dark puddle in the middle of the milk. Now, dip a cotton swab into dish soap, and it into the middle of the food place coloring. You will see the colors quickly move to escape from the soap, making interesting and beautiful patterns. This happens because th

19、e dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving
