For a fun and groovy spring break experiment my partner and I made a lava lamp!
After a couple tests to see how food coloring would react in our lava lamp, we got a tall Voss water bottle and filled a quarter of it with water. We then then filled the other 3 quarters of the bottle with vegetable oil, leaving a small amount of room at the top. We waited for the oil and water to separate and then added a couple drops of blue food coloring and one Alka-Seltzer for extra bubbly fun.
The bubbles were a little more scattered than we hoped, but it looked like a real lava lamp for some time!
We focused on the question, "what properties keep the water from mixing with the oil."
