Make a lava lamp with your preschooler, and your preschooler will love science experiments!
Lava lamps are simple to make. Like crazy easy.
My kids love experimenting! And I love watching them discover the world through science and creativity.
Easy DIY Lava Lamp Science Experiment for Kids
Even I was shocked at what a big hit this easy DIY lava lamp science experiment was with the boys. Just 5 simple supplies are all you need to DIY your own!
To DIY your own lava lamp science experiment, you’ll needL
- Vegetable oil (or get a clear oil)
- Food coloring of your choice
- Alka-Seltzer Tablets (as many as you choose, the more the merrier!)
- Clear container (the taller and skinnier, the better the effect)
Don’t have Alka Seltzer? See how to make a lava lamp without Alka Seltzer!
4 Simple Steps to Science Fun & Fizzies
- Fill the container with 2 parts oil, 1 part water, leaving some room at the top of the container for a little bit of bubbling
- Drop in a few drops of food coloring
- Add an Alka-Selzer Tablet, start with 1/4 or a half a tablet to begin with
- Watch is fizz and bubble up to the top!
We did three containers of lava lamps. Three different colors, for triple the lava fun!
It took a lot of oil, though. I wish I had more on hand because I didn’t quite have 2/3 for each container.
The oil is essentially the lava lamp portion, so it would have been nice to have more of it. But it still worked!
I also wish I had clear oil on hand instead of vegetable oil. But I’m not sure what kind of oil besides baby oil is clear. Any suggestions?
Henry dropped in tablet after tablet. Over and over, watching it bubble up!
He used the entire box of Alka-Selzer just for this experiment!
The green one really captured his attention.
Maybe because it’s his favorite color. Or maybe because it was the tallest and skinniest, so it had the best reactions.

It was even interesting from the top of the bottles. Or, at least Henry thought so.
Once we were starting to run out of Alka-Selzer tablets, we started combining the colors and making them bubble together.
We were surprised to see that the colored bubbled remained separate!
Instead of red bubbles mixing with blue bubbles to make purple, everything stayed red or blue. Cool, huh?!?!
Can you see the little red ones in the mix of the big blue bubbles?
We tend to do a lot of science in our house, with tons of easy experiments happening all the time.
The boys love anything that fizzes and bubbles. We also really like this baking soda and colored vinegar science experiment for kids.
