10 Steps to Follow: How to Make a Lava Lamp With Baby Oil 

Step 1:

Fill the baby oil container halfway up with water. Add about four drops of food coloring to give it a nice color.

Step 2:

Fill the rest of the container up with baby oil. Screw on the top, but make sure you don’t tighten it too much, or it won’t work!

Step 3:

Lay down your Alka-Seltzer and wait for it to dissolve in the water.

Step 4:

While you’re waiting, fill your lava lamp container about ¼ complete with water. Then slowly add oil until it’s filled to about an inch from the top of the container.

Step 5:

As soon as the Alka-Seltzer is done fizzing and has dissipated into the water, add it to the baby oil container.

Step 6:

Watch your lava lamp get created! You can adjust how high or low you want it to go by screwing on the top of the baby oil container on the top.

Step 7:

Enjoy your very own lava lamp! This is a great project to do with your friends, family members, or even alone.

Step 8:

If the lava in your lamp slows down or stops altogether, add in another Alka-Seltzer tablet and watch it start up again!

Step 9:

Clean up all of your supplies if you want to clean them or keep this experiment going for a while.

Step 10:

Make sure to put all of your supplies away to avoid messing up.

Some Tips and Suggestions:

  1. There’s a difference between vegetable oil and baby oil. Vegetable oil is not as viscous and won’t work for this project.
  2. It may be easier to get the lava moving if you warm up the lamp by letting it sit in sunlight or holding it with your hands for a minute before turning it on.
  3. If you want to add color, add a few drops of food coloring when you add the water.
  4. This project may take around 30 minutes to complete. It will take longer if you don’t have all the materials on hand and need to run out for them or if your lamp is very cold and takes time to warm up.
  5. If you want to use another type of oil, such as olive oil, be aware that it will solidify in the lamp when the water evaporates.

Things to Consider When Making a Lava Lamp With Baby Oil:

Lava Light Effects in Dark Room
  1. Lava lamps are much smoother to make with mineral oil rather than baby oil. If you do use baby oil, clean the lamp the next day to avoid any possible residue.
  2. This is not a completely safe activity for all ages! Make sure whoever is helping has adult supervision at all times.
  3. It takes about 1 hour for the lamp to start working.
  4. The best way to see the lava effects is with a black (or dark) light and in a dark room.
  5. The lava lamp works by using heat to change the density of the baby oil. The lava appears when the lamp gets warm, and the baby oil becomes less dense. When it cools, the baby oil is more viscous and sinks back down.
  6. Clean lamps will result in better lava flows than dirty lamps. If you don’t clean your lamp for an extended period, you will most likely have to start over because the oil will thicken and stop moving.
  7. Baby oil is more efficient than water in creating this lamp because it has a lower surface tension, making it easier to form pearls when transitioning from the warm area to the cold area. This allows for better lava flows.
  8. Mineral oil or vegetable oil could also be used but may not produce dramatic results as baby oil. Also, if you use water instead of baby oil, the lamp will work, but the lava won’t show up so dramatically without a black light.


Making a lava lamp is very easy and can be done with only a few things. For the first thing you need, you will need some baby oil or mineral oil. This substance does not emit any fumes, so it’s safe to use around kids and pets. You also want to make sure that this substance is obvious before using it for your lava lamp project!

The next ingredient you’ll need is white vinegar which helps create bubbles on top of the water; we recommend using about two tablespoons worth of vinegar per quart of water. Then, take one container (we suggest using an old glass jar) large enough to hold your desired amount of water but small enough to have no room left over.
