Lava Lamp Without Alka Seltzer
If you dont have all the ingredients on hand you can make a few substitutions.
Instead of vegetable oil you can use baby oil. We found it created a lot of bubbles and the clarity of the lava lamp was not as good, but it does still work.
Next, if you dont have Alka Seltzer, you can make your own mix. If you ever make bath bombs like us, you already have the ingredients on hand! Simple mix 2 parts baking soda with 1 part citric acid. Add a teaspoon of the mixture and watch the reaction go! The best part is how this helps kids understand that it is once again an acid-base reaction charging our lava lamps. We love those acid-base reactions!
Now, what can you use instead of water? Well we came up with a cool solution that gives our homemade lava lamps glow power!

Oil And Water Experiment
Children will be fascinated by how the oil & water didnt mix! They can shake up the jar and watch as the two substances will go back to oil at the top and water at the bottom. You can give them this simple explanation on why oil and water dont mix:
Oil molecules are only attracted to other oil molecules and water molecules are attracted to water molecules. So they dont mix together. The reason the oil floats on top is because the oil is less dense than water.

Main Types Of Volcanoes
- These are the simplest type of volocano that is made up of cinders, which are smaller broken-up pieces of hardened lava. As rising magma shakes the ground, pressure sends gases, molten rock, and ash into the air which allow the molten material to cool quickly in the air. As the molten material cools, it falls and breaks to form bubbly cinders around the vent.
- The vent is characterized by a crater-shaped depression at the top of the cinder cone volcano. Eruptions of lava flows come out from the vent, and repeated flows that build-up along an eruptive vent can even form stratovolcanoes.
Conical Composite or Stratovolcano
- Composite volcanoes are often referred to as stratovolcanoes. These types of volcanoes are usually what make up the tallest mountains we see, rising to heights of over 8,000 feet . They are tall and steep because of repeated lava flows, volcanic ash, cinders, blocks and bombs, which are larger debris erupted from these volcanoes.
- These types of volcanoes are highly eruptive because of thick, silica-rich and gas content in its magma.
- These types of volcanoes are almost entirely built out of fluid lava flows, which pour out in all directions from the vent. As these lava flows build-up on top of each other, they create a gentle slope. These volcanoes build-up slowly over time and over thousands of lava flows.
- Place 2 tbsp of vegetable oil into each container of water.

How Does It Work
To begin, the oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called intermolecular polarity. That term is fun to bring up in dinner conversation. Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules, they get along fine as well. But the structures of the two molecules do not allow them to bond together. Of course, theres a lot more fancy scientific language to describe density and molecular polarity, but maybe now youll at least look at that vinegrette salad dessing in a whole new way.
When you added the tablet piece, it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the colored water with them. When the blob of water reached the top, the gas escaped and down went the water. Cool, huh? By the way, you can store your Blobs In A Bottle with the cap on, and then anytime you want to bring it back to life, just add another tablet piece.
MAKE IT AN EXPERIMENT
The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:
Make An Easy And Fun Glow In The Dark Lava Lamp
- Ph.D., Biomedical Sciences, University of Tennessee at Knoxville
- B.A., Physics and Mathematics, Hastings College
Use common household ingredients to make a safe lava lamp that glows in the dark. This is a variation on the popular oil and water lava lamp, except instead of coloring water with food coloring, you use a water-based liquid that glows.

Glowing Lava Lamp Materials
- clear plastic bottle
- vegetable oil
- glowing water
- Alka-Seltzer tablets
- black light
Whether the lava glows on its own or glows under a black light depends on the materials you choose. If you use glowing paint, expose the lava lamp to bright light, turn out the lights, and it will truly glow in the dark. However, the easiest and brightest liquid to use is glowing highlighter ink. If you aren’t sure how to get the ink out of the highlighter, I have instructions. This ink will glow when exposed to black or ultraviolet light.
A Final Quick And Easy Lava Lamp Experiment
If you are still stuck for supplies and need a really simple way of making a lava lamp. Here is an easy way!
Place 2 tablespoons of baking soda in the bottom of a mason jar. Pour oil into the jar. In a second container add vinegar and a few drops of food colouring, mix. Now, using a dropper, add a few drops of coloured vinegar to the top of the oil and watch the reaction!
As the bubbles float through the oil down into water the bubbly reaction will be triggered!
Have fun creating lava lamps!

Why This Science Experiment Works
The water and oil do not mix and the oil doesnt change color because the food coloring is water soluble. The Alka Seltzer reacts with the water to make bubbles of carbon dioxide. The bubbles attach themselves to the blobs of colored water and bring them to the top of the glass. When the bubbles pop the blobs of colored water fall back to the bottom of the glass.
This lava science experiment is sure to WOW your kids. They may even ask you to do it over and over again like mine did!
The Science Behind How It Works
The globules form because oil and water are immiscible. The oil has a nonpolar nature, while water is a polar molecule. No matter how much you shake the bottle, the two components will always separate.
The movement of the ‘lava’ is caused by the reaction between the seltzer tablets and water. Carbon dioxide gas forms bubbles, which rise to the top of the liquid and cause it to circulate.
The glow of the lava comes from either phosphorescence or fluorescence, depending on the chemical you used. Fluorescence occurs when a material absorbs energy and almost immediately releases light. A black light is used to make fluorescent materials to keep glowing. Phosphorescence is a slower process in which energy is absorbed and released as light, so once a phosphorescent material is charged with light, it may continue to glow for several seconds, minutes, or even hours, depending on the specific chemicals.

Learn how to make a lava lamp experiment without Alka Seltzer! Its a fun science experiment to do with your children.
Have you ever wanted to know how to make a lava lamp without Alka Seltzer tablets? I often find myself without those on hand!
Weve made lava lamp experiments in the past using Alka Seltzer tablets.
We actually just did it again with Louis for the first time. It was fun to see his reactions!
But, the fun didnt last long.
I ran out of Alka Seltzer fast. I only had 2 tablets to begin with.
It wasnt even a day later that a member of my Facebook group, The Huddle, asked how to make a lava lamp without Alka Seltzer.
That got me searching to find an answer! I found an awesome video here with an explanation of what to do.
Then we had some fun making lava lamp experiments again, but this time, without Alka Seltzer tablets!
I also finally found some skinny glasses to use. I kept looking for bottles, but once I thought of using glasses, skinny ones were easy to find!

How To Make A Lava Lamp Without Alka Seltzer Tablets:
I filled each glass about two-thirds to three-fourths full with water. Another plus of this concoction is that its mostly water and not nearly as much oil!
From there, the boys took over. They chose their color of food coloring and put a couple drops in each glass.
I do recommend keeping it on the lighter side to see the lava lamp bubble effect better.
Next, fill the rest of the glass with oil. Leave a good half an inch at the top of the glass.
We filled ours too full the first time we tried it.
And then the fun begins, and this is the secret ingredient to make a lava lamp without Alka Seltzer.
At first, its crazy bubbly as the salt finds its way to the bottom. That salt sinks fast!
But then the slow part begins, the true lava lamp part, as the bubbles slowly emerge from the salt at the bottom finding their way to the top.
I actually think this way to make a lava lamp without is much more like the lava lamps we used to have in our bedrooms.
The boys truly enjoyed watching the effects of there lava lamp experiments without alka seltzer!
And this was all before a day at school.
They may have gotten up super early that day
Heres a quick video of Louis dumping in the salt to create the lava lamp effects. I wish I could show it better!

While density can be a tricky concept for younger scientists to understand right away, this DIY lava lamp experiment is a great opportunity to observe density in action and make some initial observations while enjoying some fizzing good fun!
- Tall, clear container
- Alka-Seltzer tablets
- Food coloring *Warning: Food coloring can stain! Feel free to substitute in washable paint such as liquid watercolor or tempera paint if youre worried about mess. Either way, mess-friendly play clothes are recommended for this DIY lava lamp experiment!
- Fill your measuring cup with 1 cup water.
- Add 10-15 drops of food coloring to your water then stir.Observe the food coloring drops as they enter the water. What do you notice? Do they float? Do they sink? Does the food coloring mix well into the water? What do you see?
- Fill a clear container ¾ of the way with canola oil.
Pour the dyed water into your clear container, along with your canola oil.
What do you notice about the water and the canola oil? Do they mix together? Which one sinks to the bottom? Is this the same as what you observed with the food coloring and water?
You can continue adding effervescent tablets as the bubbles slow.
