Lava lamps are the groovy colorful lamps you remember seeing as a kid and there’s a super easy way to replicate the look at home that makes them fun for kids and a cool STEM science experiment to boot.

See how to make these easy DIY Mason jar glitter lava lamps with some common kitchen ingredients and glitter for some extra sparkly fun!

Watch the video below to see how cool they are in action and read more below for the specific instructions on how to make them and make sure to subscribe to our YouTube channel!

DIY Mason Jar Glitter Lava Lamps – Materials:

– Mason jars

– Vegetable oil

– Water

– Food coloring

– Antacid tablets (the ones that bubble when in contact with liquids, like Alka-Seltzer tablets. Tums will not work)

– Glitter (optional)


Step 1. Fill about 1/3 of your jars with water. Add vegetable oil leaving some room at the top to make sure the mixture doesn’t bubble over.

Step 2. Add your food coloring, as much as you want (feel free to mix up the colors).

Step 3. Add glitter. This is optional, but adds an extra visual and sparkly element kids love.

Step 4. Add your antacid tablets. Go slow at first, one by one to watch the bubbles appear. Then you can add a couple at a time and watch the bubbles go fast and furious. My kids couldn’t get enough of this!

You can turn off the lights and have your kids shine a flashlight into the jar to watch the cool effects in the dark. This was fascinating for my kids.

So what’s the science behind it? Oil and water don’t mix so when the antacid tablets reach the water, they release carbon dioxide bubbles which rise up through the oil creating cool colored bubbles in the process.

These DIY lava lamps were so easy to set up and make such an interesting and visual experiment for kids. My kids had a blast making them!

*Note: please make sure to not keep the lid on while the antacids are bubbling inside. Make sure to supervise your kids when doing this craft, which is what we did. When not in use, you can place the lids back on and keep the jars for quite a while and re-use again. Also according to our readers, Tums will not work. It needs to be an antacid that will dissolve and create bubbles like Alka-Seltzer.
