Love to play with bubbles? Well, in this dry ice bubble experiment we are going to show you how to make a giant bubble using dry ice and soapy water. To do this experiment you surely require some dry ice. You can either buy dry ice from your neighborhood lab supplier or make dry ice all by yourself. Handling dry ice needs proper care and we strongly recommend an adult’s supervision.
Try it yourself
- Warm water
- Cloth or Leather gloves
- Dish soap
- Cotton fabric strip
- Small cup
- Adult supervision
Clear and make some space as your experiment to be executed. Do not forget to use your gloves to escape frostbite. Arrange the materials you needed for this experiment in the work space.
Step 1: Take the small cup and mix two tablespoons of dish soap and one table spoon of water. Stir well.
Step 2: Immerse the cotton fabric strip in the soap solution. Make sure that the cloth is completely submerged.
Step 3: Take the bowl and fill the bowl until half with warm water.
Step 4: Place two or three dry ice in to the bowl. You will notice that the bowl will start experiencing a fog from the bowl and it will slowly cover the bowl, if left unattended.
Step 5: Take the soapy cotton strip over the bowl and carefully draw it over the bowl neck. The soap will create a bubble over the bowl and it will slowly increase by size. in a few seconds you will have your giant dry ice bubble.
Do you know how a giant bubble formed during your dry ice bubble experiment? Well, you just trapped cloudy CO2 under the bubble by a thin layer of soap solution. If you poke the bubble to pop, you will see the smoke like carbon dioxide escaping from the bowl and spreading all around. There are more dry ice experiments that you can try at your home.
