In reply to Chelsey. Thanks for the further explanation. We're using this for a homeschool lesson and I like being able to answer all of her questions.

In reply to Anonymous. Glad you enjoyed it and thanks for the comment! The food coloring is water soluble. It will not mix with the oil, but will mix with the water. Since it was added after the oil in small amounts, it remands suspended in the oil and won't mix with it. (If you squeeze a ton at once- which my son happily tried- it will go directly into the water.) The salt is heavier than both the oil and water, so when it lands onto the drops of food dye, it pulls the dye and blobs of oil down with it into the water where the dye will spread.

I tried this and it works! The explanation, however, doesn’t seem thorough enough? Does the Salt make the food color’s density greater, therefore, bringing the color down into the color portion?

Loved it!! Tried with our little guy tonight. We added pepper after the salt, which was pretty cool! The pepper floated in the oil and when we took a plastic stick to push the pepper down it stuck to the stick until we pulled the stick back up.
