Hi this is Scott Thompson from expertvillage.com, and today I'm going to demonstrate a way to build an ocean in a bottle, and demonstrate that some solutions just do not mix. Those substances will start kind of classifying themselves based on density: the oil will go to the top; the water will stay near the bottom. And because the food coloring is water-based, it only mixes with the water. That will be a marker for us, it will show us where the water is in the ocean. Turn it over a few times. Get it really mixed up, but not too much. This is the part that the students really like. And you give them their choice of whether they want to do red, I got a yellow one here that I made earlier, or a green one, or a real natural—I guess for an ocean—blue. And that is ocean in a bottle.
