Homemade Lava Lamp Activity Water Oil Density Science
Step 1: Gather Your Supplies
Before we can get started, you'll need to gather a few supplies. Here's what you'll need:
- A clear plastic or glass bottle
- Vegetable oil
- Water
- Food coloring
- Alka-Seltzer tablets
Make sure to choose a bottle that is at least halfway clear so that you can see the lava lamp action happening inside. And if you don't have any Alka-Seltzer tablets lying around, you can always substitute them with baking soda and vinegar for a similar chemical reaction.
Step 2: Fill Your Bottle
Fill your bottle about halfway with vegetable oil, making sure to leave enough room at the top for the water to be added later. You can also add a drop or two of food coloring to the oil to give it a nice pop of color (or you can leave it clear, but that's just boring).
Step 3: Add Your Water
Next, it's time to add the water. But be careful! Adding water directly into the oil will cause the two to mix together and ruin your lava lamp effect. The trick is to pour the water in slowly and directly into the middle of the bottle. The water will sink to the bottom and form a separate layer underneath the oil.
Step 4: Add Your Alka-Seltzer Tablet
Now for the fun part. Drop one or two Alka-Seltzer tablets into the bottle and watch the magic happen. The tablets will fizz and bubble, causing the water to move up through the oil to the top of the bottle. Once the tablets dissolve, the water will sink back down to the bottom and the process will start all over again.

Tip: Use Different Sized Bottles
Trying out this experiment in different sized bottles can create different size and color patterns. Try using a tall, skinny bottle for a narrow and vibrant column of bubbles, or try a shorter, wide bottle for a more dispersed and colorful pattern.
Idea: Experiment with Colors and Textures
Try adding different kinds of food coloring to create a rainbow of colors, or add glitter or small beads to create a different texture. The possibilities are endless!
How To: Clean Up
Once you're done with your lava lamp, you'll need to properly dispose of it. Pouring the oil and water mixture down the drain can cause pipes to clog and damage sewage systems, so it's important to dispose of it properly. The best way to do this is to pour the mixture into a sealable plastic bag and throw it away in the trash. If you added any Alka-Seltzer tablets, be sure to dispose of them properly as well.
And there you have it, folks. A homemade lava lamp that will provide endless hours of mesmerizing entertainment. So gather your supplies, round up your friends and family, and show them your newfound skills as a mad scientist. And, hey, if all else fails, at least you have a cool new decoration for your room, right?
