Annelise!

Experiment: Smokey Bubbles

Objective: What happens when you put dry ice in soapy water?

Materials:  plastic container, water, dish soap, dry ice

Our scientist has all of her materials ready & her safety gear on!

First she added dish soap to the hot water.

Then she stirred and mixed it up.

After that she CAREFULLY carried dry ice over...

...and placed it into the soapy water. 

Once the dry ice settled in the water, bubbles started forming!

The bubbles multiplied...

...and multiplied!

Our scientist got very excited as the bubbles starting spilling out of her container!

Wow, Annelise!  What fun that was!

We were all able to touch the bubbles, too!

 A BIG thank you to Annelise and her assistant, Dad, for such a fun morning learning about carbon dioxide gas!

Conclusion: When carbon dioxide gas is released from the dry ice, it causes a chemical reaction which makes the water bubble.  Carbon dioxide gets trapped in the soapy water.  Vapor releases and it appears as smokey bubbles.
