Extreme Science: Floating Bubbles

Posted: Updated:
What you will need:
  1. Fish tank or large container
  2. Dry ice  *** Use caution – never handle dry ice with your bare skin! ***
  3. Bubble solution
  4. Bubble blowing wands
  5. Adult supervision

Procedure:

1) Using protective gloves, place your dry ice inside the fish tank.** Dry ice is minus 115 degrees and will cause what is called a cryogenic burn if you handle it with your bare skin. Make sure that you are setting a good example for the kids by handling it with the proper care! Let the dry ice set undisturbed for about 10-15 minutes. If you are using a glass fish tank, you may want to lay down a towel to put the dry ice on as it is minus 115 degrees to prevent any possible cracks in the glass due to the extreme cold.

2) Carefully begin to blow some bubbles into the tank over the dry ice.

What is going on?

Dry ice is made from carbon dioxide gas. Since there is no liquid in dry ice, it does not “melt.” Since dry ice is actually made from frozen carbon dioxide gas, as it warms up it will change from a solid back to a gas. We call this process sublimation. Since carbon dioxide gas is about one and a half times heavier than the air around us, it will settle in the bottom of the tank. You can't see this layer of gas until you begin blowing bubbles into the tank. Since the bubbles are filled with air, they are lighter than the gas that has now built up in the bottom of the tank which will cause your bubbles to “bounce” across this layer of gas.

Try this:

I have seen where bubbles will freeze instantly if they come in contact with the dry ice since it is so cold. See if you can instantly freeze some bubbles on your dry ice. Again, please be careful not to touch the dry ice with your bare skin as it will cause
