Answer 2

Answer:

Explanation:

Step 1: Fill a glass about two-thirds full with tap water.

Step 2: Add a couple of drops of food coloring and stir.

Step 3: Add cooking oil to almost fill the glass. Watch carefully!

Now for the really neat part!

Step 4: Use a salt shaker to pour salt over the mixture. Watch the oil fall and rise. Continue adding salt to keep the movement going.

What is happening? Here’s the science:

Salt is more dense (heavier) than oil or water so it is going to sink. As the salt sinks it pulls blobs of oil down with it. When the salt starts to dissolve, it releases the oil. The oil rises back to the surface. You get dancing oil!
