22. Questions! Swirly Milk. –What happened to the milk? Why? Copyright © 2010 Ryan P. Murphy

23. How Swirly Milk Works –When you introduce detergent to the milk, several things happen at once. The detergent breaks the surface tension (skin on the top of the water) Food coloring is now free to flow through the milk. Detergent reacts with milk…Creates motion Detergent breaks up fat in milk pushes color around. Continues for awhile and then stops. Copyright © 2010 Ryan P. Murphy

143. Which is polar, and which is non-polar? Wax Paper Water Droplets

144. Which is polar, and which is non-polar? Wax Paper = Non-Polar Water Droplets Polar

145. Which is polar, and which is non-polar? Wax Paper = Non-Polar +/+ Water Droplets Polar

146. Which is polar, and which is non-polar? Wax Paper = Non-Polar -/- Water Droplets Polar

147. Which is polar, and which is non-polar? Wax Paper = Non-Polar -/- Water Droplets Polar +/-

148. What did the molecules attach to? Why? Wax Paper Water Droplets

149. What did the molecules attach to? Why? –Answer: Because the water molecules are polar, they attached to themselves and stayed in a drop. The wax paper is non-polar, so the water did not mix with it. Water Droplets

150. Many products use polarity to help waterproof materials.
