Snowstorm in a Jar Winter Science Experiment for Preschoolers
This STEM activity makes a great addition to a Winter theme or snow study for homeschool kids. It’s simple and safe enough for preschoolers, and engaging enough for older kids, too! The perfect big family science experiment for the Winter season.
While learning about snow this Winter, I set out to find a science experiment that emulated a blizzard. I just knew it had to exist!
And, wouldn’t you know it, this snowstorm in a jar experiment was just what I was looking for. It doesn’t snow down here in Texas very often, and most Winters go by without a single snowflake finding it’s way to our yard. This was the first year that my son even noticed that we don’t get to partake in the snowy fun, and studying snowflakes wasn’t exactly an easy topic to cover since neither of us have any real-world experience with it.
So, while we may not have gotten any real snow this year, this Winter science experiment filled the hold left in our snowless hearts.

Snowstorm in a Jar Preschool Science Experiment
Here’s what you’ll need for this Winter Science Blizzard Experiment:
- Baby oil
- Washable white paint
- Alka Seltzer tablets
- Optional: glitter
To make it without baby oil, you can substitute cooking oil, but I don’t recommend it at all because of the color.
You can also add food coloring to simulate the blue sky, but we skipped this step.
How to Make a Snowstorm in a Jar:
1. Fill jar 1/4 of the way with water.
2. Mix in white washable paint until it looks like milk. It shouldn’t take much at all.
3. Fill the jar the rest of the way with baby oil, and add glitter.
4. Allow the oil and water to separate and settle.
5. Break an alka seltzer tablet up into a few pieces and allow your child to drop them into the jar.
6. Watch the snowstorm!
