Rain Cloud in a Jar

Good afternoon scientists! My little scientist and I have been busy making our very own rain cloud today! Help your little scientist make one too.

Materials Needed

Shaving Cream (Not Gel)

Blue Food Coloring

Clean Empty Jar (Plastic or Glass)

Bowl or container to hold dyed water

Pipette, Water Dropper or Eye Dropper


Optional: Gloves and/or apron/paint shirt


  1. Fill your chosen jar about halfway up with water
  2. Squeeze Shaving cream on top of the water, stop before it reaches the top. If yours looks like it has a lot of gaps use your finger to gently push the shaving cream down to smooth it out (I had to do this each time we made the cloud). Apply more shaving cream if needed.
  3. Fill your bowl or container with water to be dyed with blue food coloring
  4. Add drops of blue food coloring to your bowl (The food coloring will stain if you get it on your hands or clothes, use gloves and apron if you are concerned about this)
  5. Mix up the now dyed water with your pipette
  6. Squeeze the ball on top of the pipette to suck in the dyed water and let go while still submerged.
  7. Squeeze out the pipette above your cloud. (Ask your little scientist to not put the pipette in the cloud or it will suck it into the pipette)
  8. Keep doing steps 6-7 until it starts to “Rain”. You will start to see blue entering the bottom of your cloud in a jar.
  9. Continue raining in your Rain Cloud in a Jar as long as you and your little scientist want or until the rain portion is dark blue throughout.
  10. Enjoy the rain with your little scientist. Mine loves this experiment and wanted to do it over and over again.

Talking Points

In this investigation the shaving cream is acting as your cloud. As the dyed water collects in your cloud it starts to oversaturate, more water is in your cloud then can fit. The collected water is just like real water from the water cycle collecting and forming clouds as Condensation, then as the cloud gets to heavy and full to hold the water it will start to “Rain” or Precipitate.
