Make your own snowstorm in a jar!
While the weather outside is creating snow flurries on the other side of your windows, you can make a winter snowstorm of your own — right at home. Gather all of the kids and interested adults, and generate a fizzy storm in a jar using ingredients you may already have at home. Here is everything you need to know about this perfect snow storm science experiment.
Snow storm project materials needed
- Water (about 1 cup)
- Baby oil
- White paint
- Blue food coloring (optional, but a whole lot of fun)
- Mason jar
- Stir stick
How to make a snow storm in a jar
- Fill your jar about three-fourths full with baby oil. In a separate bowl, blend water and a few tablespoons of white paint.
- Add as much glitter and blue food coloring to the oil as you’d like, and then top off the jar with your water and paint mixture.
- Drop your Alka-Seltzer tablet into the jar, and take a step back. Watch the storm whirl in the jar right before your eyes!
The science behind the storm
Here’s the science behind this storm science experiment. Because oil is less dense than water, the water will naturally sink to the bottom of the jar. When the Alka-Seltzer is dropped into the jar, its interaction with the water creates pressure in an upward direction, and the oil pushes it back down. The back and forth pressure is part of what creates the snowstorm.
The other element is the interaction between water and sodium bicarbonate in the Alka-Seltzer, which generates carbon dioxide gas. The combination of these factors creates a blizzard every time!
Whether the temperature is dropping outdoors or you just want to bring a bit of winter snow fun to a summer day, your snowstorm in a jar is a foolproof way to get kids interested in science. Learn how to make a storm in a jar with under $10 in ingredients, a whimsical lesson plan awaits!
