Dry Ice Balloon Blast Science Experiment for Kids

Dry Ice Balloon Blast is a fun science experiment where kids can inflate a balloon using dry ice! Dry ice is frozen carbon dioxide and quickly sublimates to carbon dioxide gas at temperatures higher than -76 deg C. In this experiment, we are going to convert the dry ice to carbon dioxide gas and inflate a balloon.

 

Safety First! Adult Supervision Required. Don’t Eat/Drink your Experiments, Wear safety goggles where ever required


Materials and tools required.

Dry Ice Balloon Experiment Step 0

In the box

  • Plastic bottle
  • Warm water
  • Small dry ice pieces
  • Balloon
  • Surgical/rubber gloves

Video on Youtube for the Experiment

What to Do!

  1. Add small pieces of dry ice in the plastic bottle with warm water. You can mix some food color.
  2. The dry ice bubbling and boiling at the bottom of the bottle thus producing carbon dioxide.
  3. Place a round balloon on the mouth of the bottle and see the balloon inflate. (CAUTION: the balloon might burst if the flow of the gas is too high.)
  4. Observe the gas filling inside the balloon.
  5. You can repeat the steps to inflate a surgical/rubber gloves.

Working Principle of Dry Ice Balloon Blast :

In this experiment, when dry ice is added to warm water, it turns to carbon dioxide gas immediately. This gas if trapped inside a balloon, inflates it! Now, you know a cool way to inflate your balloon.

Dry ice turns directly into gas without going through the liquid phase, this process is called sublimation. When dry ice is dropped in warm water, it creates a ‘fog’ which is carbon dioxide gas and water vapour. When the balloon is attached at the mouth of the bottle, this ‘fog’ gets trapped inside the balloon and inflates it. You can get creative and try inflating any another inflatable rubber item like surgical gloves!

You’ve heard of helium balloons but now you have carbon dioxide balloons too! The only difference is that it doesn’t go up like a helium balloon as carbon dioxide is heavier than helium.
