Video Demo: Diffusion
Wednesday, June 10, 2009 at 11:37AM
See 2 video demonstrations of diffusion in action. The first video shows a drop of food coloring diffusing through water. It is a video that is time lapsed at 1 frame/15 seconds. The second video shows a Ziploc bag of iodine placed into a beaker of starch water. It is a video that is time lapsed at 1 frame/30 seconds. The iodine diffuses out of the bag and into the starch water. Where the iodine is diffusing the starch water turns a dark blue.

Did the starch move outside of the baggie?
What is happening to the iodine particles and starch particles around the bag?
