For my mini projece I watched oil rise to the top of a cup of water and simutaneously watching food coloring or dye drop to the bottom. The dye created a sea of colors while dropping to the bottom.
What you'll need:
1. A cup of water
2. about 2 tbls of oil
3. food coloring/dye (try to use a variety of colors)
4. a seperate cup (no ingredients in the cup)
To do:
First you will need to get a cup of water. Make sure the cup is not completey full of water, you want to leave about half of the cup empty. After getting that cup of water, pour the 2tbls of oil in a different seperate cup. Once the oil is in a different cup, take your choice of dye a put a few drops of it in the seperate oil cup. Make sure to use a couple of colors to see the full effect of the experiment. After the dye and the oil are together, carefully pour the oil mixture in the water cup. What happens?
Scientific explanitions:
When you finally pour the mixture in the water, usually the oil will dip to the bottom then rise to the top with the dye. After the oil mixture rises to the top, ususally, the dye in the oil becomes heavier than the oil and sinks past the oil. It leaves its circular form and drops in to the water leaving streaks in the water. This creates the color streaks , when you have one or more colors it tends to work better. This happens because the dye becomes denser than the oil and is a little bit denser than the water ad sinks to the bottom creating the water streaks and pool of color at the bottom of the cup.
