States Of Matter Balloon Science Experiment
In this fun and easy science experiment, we’re going to use a balloon to investigate if a solid plus a liquid can equal a gas?
- Baking Soda
- Clean and dry bottle (Glass or plastic)
- Small funnel
- Using the funnel, add two tablespoons of baking soda to the balloon.
- Now pour four ounces of vinegar into the bottle.
- Put the balloon over the mouth of the bottle. Two people make this job easier as one can hold the bottle steady while the other puts the balloon onto the bottle.
- Now lift the balloon and allow the baking soda to fall into the vinegar.
- Observe the chemical reaction and the effect on the balloon.
How it Works:
When baking soda (solid) and vinegar (liquid) are combined, an endothermic chemical reaction occurs. This chemical reaction creates carbon dioxide (gas). Since the balloon is stretched over the mouth of the bottle, the carbon dioxide gas can not escape. The carbon dioxide gas creates pressure in the bottle and inflates the balloon.
Make This A Science Project:
Try different amounts of baking soda and vinegar. Try cooling or heating the vinegar to test if the temperature effects the chemical reaction. Try different sized balloons and bottles.
