Tug of War

This was a very cool experiment!
We used rubbing alcohol, food coloring and water to demonstrate how the water and alcohol molecules react when they come in contact with each other.

They immediately seperate! They are both pulling away from each other in a tug of war.
The water moves away and takes some of the alcohol with it.
The water forms a ridge around the alcohol.


Eventually, the water wins and takes over the alcohol.


You have to watch the video to see the pulsating ridge of water as the two different molecules pull on each other!
So cool!
Thanks again, Janice VanCleave for another fun and educational science experiment!
