What makes dish soap separate food coloring in a bowl of milk?

Answer 1

It is a science experiment on surface tension in liquids, where drops of food coloring are placed into a shallow plateful of milk. The coloring drops (being lighter, water-based liquids) will usually just stay put due to the surface tension of the milk (which is a denser colloid of fat molecules).

You can dip a cotton swab in dish soap, then gently touch the swab to the surface near the drops. Or you can drop a drop of soap into the center of the milk.

Adding a little soap will break the surface tension of the milk by dissolving some of the fat. When this happens, the moving surface of the milk will disperse the food coloring drops away from the soap, possibly even down into the milk. You can get a spectacular moving color display as the coloring drops break up and fan out.

Answer 2

because milk has certant chemicals that react to dish soap but it also depends on what dish soap your using like dawn soap has an effect on the milk if you read the labels look up the chemicals and see why it doesnt attracts and whny it replls

Answer 3

Well, the chemicals in milk repel from the chemicals in certain dish soaps. The food coloring is mainly what shows the movement in the milk.

Answer 4

Soap molecules bond to oils and fats, trapping them in a molecular matrix. This has the effect of releasing some of the watery base (whey) of the milk while bonding to the fats (curds).

Answer 5

This is a physical reaction to urine

Answer 6

yes it is a chemical reaction
