  1. Spinning Molecules Make a Rainbow By Tommy Epp

  2. Purpose • What milk is best to make a soap molecule dance?

  3. Hypothesis • The colors will dance because the soap molecules like fat and move to it. • I think the best colorful design will appear in the whole milk.

  4. Procedure • Get the following: • Liquids w/ a range of fat(water, skim, 1%, 2%, whole, cream) • Shallow plate • food coloring: red, green, yellow, and blue • Q-tips • dish soup • Pour a thin layer of milk in plate. • Prop 1 drop of each food coloring in the milk • Put a drop of dish soap on a Q-tip • Place Q-tip in milk • See what happens; Record observations

  5. Most of the color went down to the bottom. It made a circle shape. Water

  6. Still had a circle shape, went a lot slower then water, had pointy pieces, no dancing Skim

  7. Very little difference from skim milk 1% Milk

  8. No circle shape Went slower than 1% milk Had a lot of spikes Maybe a bit of dancing 2% Milk

  9. No circle Went slower than 2% milk Star shape No dancing Whole

  10. Different than all the others A LOT of dancing Moved VERY, VERY slowly Cream

  11. Conclusion • My hypothesis was partly wrong • I said whole milk was best but really cream was better • I think cream was better because cream had cooler designs • The designs danced more, had more curly, bumpy edges • I also liked cream because it was slower • I said the soap molecules went to fat • Cream has more fat so logically it would be better

  12. Research • Spangler, Steve. Naked Eggs and Flying Potatoes. Austin: Greenleaf, 2010. • Parents (They answered some questions.)
