Simple ingredients. Simple directions. BIG results. TRY IT OUT!!
The following experiments are geared more towards the younger crowd, but I never did them growing up, so I am doing them now with my kiddo.
Overview of materials for all three experiments
SNOWSTORM IN A JAR (scroll down for written directions or follow the video above)
Glitter (optional, just pretty to watch swirl around)
RAIN CLOUD IN A JAR (scroll down for written directions or follow the video above)
A jar (we recommend a wide mouth shallow one)
Blue liquid watercolors (you can also use water with food coloring just as easily! You can also experiment with different colors and create a rainbow cloud and rain! How pretty would that be?)
TORNADO IN A JAR (scroll down for written directions or follow the video above)
SNOWSTORM IN A JAR
Step 1. Add your baby oil to the jar about 3/4 full.
Step 2. Mix white paint with a bit of water. To be honest we didn’t exactly measure this, it was a few squirts of white pain with about 1/4 – 1/2 cups of water. The exact measurements don’t matter much here as you just want to have a thin water/paint mixture. This is a great time to test out a hypothesis – what happens if you add equal parts paint/water or more paint to water ratio?
Step 3. Add your white paint to the baby oil.
Step 4. Add glitter for some fun visual effects (optional).
Step 5. Drop your Alka-Seltzer tablet one at a time in the jar. Watch as the white paint/water mixture bubbles up from the effervescent effects of the Alka-Seltzer.
RAIN CLOUD IN A JAR
Step 1. Add water to your jar leaving room at the top for shaving cream.
Step 2. Squirt a few big blobs of shaving cream to fill the top of the jar.
Step 3. Add your liquid watercolor in a bowl and suck up a bit with a pipette. Drop the liquid into the shaving cream.
Step 4. Watch and observe the “rain” or liquid watercolor seep down the shaving cream cloud.
TORNADO IN A JAR
Step 1. Pour water into your jar almost to the top.
Step 2. Add a small drop of dish soap. Not too much or else there will be too many bubbles and it will be hard to see the tornado.
Step 3. Add some glitter (optional but cool to see it swirl).
Step 4. Cap your jar and make sure it’s tight!
Step 5. Shake your jar vigorously. First we shook it up and down, then side to side. Set the jar down and watch closely for the tornado forming in the jar!

(10/2/20 update from Homeschooling-Mommo: We had to alter elements to achieve the desired results. 2 drops of dish soap and shake it up in a circular motion – not up/down, side-to-side. Don’t use a lot of glitter or you won’t see the funnel.)

Before you go…
Check out this site (https://www.weatherwizkids.com/weather-experiments.htm)! It has a bunch of experiments that might appeal to you and your kiddo(s). I know I’ll be completing some with my child. Below is one I think would be nifty to try out.
- glass jar
- ice cubes
Fill up the jar completely with hot water for about a minute.
Pour out almost all the water, but leave about one inch in the jar.
Put the strainer over the top of the jar.
Place a few (3-4) ice cubes in the strainer.
Watch what happens!
The cold air from the ice cubes collides with the warm, moist air in the bottle causing the water to condense and forming an eerie fog.
(10/2/20 update from Homeschooling-Mommo: This experiment did not work. It made condensation, but not fog. Renamed it above.)
