One of the coolest experiments I’ve tried involved creating a homemade lava lamp! It was a fun way to explore density and the interaction of different substances. Here’s how it worked:
Materials: I used a clear plastic bottle, water, vegetable oil, food coloring, and Alka-Seltzer tablets.
Procedure:
I filled the bottle about a quarter full with water and then added some vegetable oil. The oil and water didn’t mix, creating a distinct layer.
Next, I added a few drops of food coloring to the water. It sank through the oil and mixed with the water.
Finally, I dropped in an Alka-Seltzer tablet, which started to fizz and create bubbles that carried the colored water up through the oil, mimicking the effect of a lava lamp!
It was fascinating to see the chemical reaction and the beautiful visuals that resulted. Plus, it was a simple way to understand concepts of density and immiscibility. What about you? Have you tried any experiments that stood out to you?
