Dry Ice Bubble Tower - Dry Ice Experiments

Bubble exerts such fascination on kids that they hardly resist the temptation to play with it. Our Dry Ice Bubble Tower is a great idea for them. In this experiment, bubbles continue coming out of the measuring cylinder forming a snake-like shape.

Age: 3+          Time: <10min


1. Beware of frostbite.
2. Adult supervision.

 Materials List 

  • Dry ice
  • Measuring cylinder (any transparent glass)
  • Washing soap
  • Food coloring
  • Water
  • Cotton gloves


Step 1/2 – Add drops of food coloring to the cylinder, add water and the washing soap.

Step 2/2 – Add a piece of dry ice into the cylinder. Watch what happens.


Why there is no bubble in my Dry Ice Bubble Tower?
—Make sure you add enough washing liquid.

 Scientific Description 

Dry ice is the solid form of carbon dioxide which is the gas under room temperature. The dry ice will sublimate (the physic process that solid turns into gas directly) into carbon dioxide under the room temperature. Because the dry ice is super cold, it will make the water vapor in the air condense. So, when the dry ice is added to a solution of soap, the dry ice begins to sublimating and the solution starts ‘bubbling’ and you have soap bubbles filled with carbon dioxide and water vapor inside! The bubble accumulates in the tube and the bubble stack high until they spill out.


1. We can use the baking soda and vinegar to produce carbon dioxide to have a bubble tower.
2. Can dry ice stay in a liquid state? If it can, how?


After the dry ice come to disappear, just pour the liquid into the sink.
