Density Tower Experiment

     Yesterday we made a density tower. We had done the experiment in Science class that day and it looked really cool so we tried it. (Thanks Mrs. Smith!) A density tower shows you if an object or substance has a greater or less density than water. (The density of water is 1.0) Vegetable Oil has a density less than 1.0 because it was above the water. Dish Soap has a density greater than 1.0 and so does honey.  We also put in milk but not where we were meant to. It was supposed to separate itself out but the dish soap and milk mixed...
Before:

After:

TRY IT! Adult supervision may be needed.
You will need:

• A clear glass/plastic container
• Honey
• Dish Soap
• Water
• Food coloring
• Vegetable Oil

Instructions:
1. Slowly pour the honey into the bottom of the container (We eyeballed it)
2. Slowly pour the dish soap above the honey
3. Put food coloring in the water so you can tell it from the vegetable oil later
4. Slowly pour the water above the dish soap
5. Slowly pour the vegetable oil above the water.

You will see that the layers stay completely separate. This is because they have different densities.
