STEM sLAB | Timber Joey creates a cloud in a jar

STEM sLAB, presented by Daimler Trucks North America, has Timber Joey learning how to make a cloud in a jar.

For this activity we will use:

  • Wide Mouth glass jar with a lid
  • Hot water (Just hot enough to steam)
  • Matches
  • Ice Cubes

 

  • To start grab your wide mouth glass jar. Pour your boiling water into the jar. Fill it about 1/3 of the way.
  • Now with the help of an adult, light a match and hold it at the top of the jar for a few seconds. After a few seconds drop the match into the jar. Quickly put the lid on the jar. This will trap the smoke particles inside.
  • Now grab a few ice cubes and put them on top of the lid of the jar. Pretty soon a cloud will form in the jar.
  • Once the cloud is created open the jar and let it out!
