How to Make Your Own Lava Lamp


We all love watching the blobs of color floating in a lava lamps. The bubbles that swirl around. They stretch, breaking into small bubbles. Then we watch as little blobs hit bigger blobs. Then the blob gets even bigger. Finally, the blob breaks apart and starts all over again.

It is fun to watch the lamps, but sometimes it cost too much to buy a lamp. So why not make your own?


Here’s what you will need:

    A clean 1 liter clear soda bottle

    ¾ cup of water

    Vegetable Oil

    Fizzing tablets (such as Alka Seltzer)

    Food coloring

Follow these steps to make your own lava lamp:

    Pour the water into the bottle.

    Use a funnel, or a measuring cup and pour the vegetable oil into the bottle until it is almost full. It may take awhile for the oil and water to separate.

    Add 10 drops of food coloring to the bottle (pick your favorite color if you like). The drops will go through the oil and mix with the water below.

    Now, break a seltzer tablet in two and put the half tablet in the bottle. Watch it sink to the bottom and wait for the blobs to begin!
    When it stops working just add another tablet piece. If you really want the full lava lamp effect, shine a flashlight through the bottom of the bottle.
