Balloon Blow-Up

Picture

​​Question: What will the solution of baking soda and vinegar do to a balloon?

​

Hypothesis: ​We think that the balloon will inflate.

Materials:

Picture
  • ​Empty Plastic Water Bottle
  • Vinegar
  • Baking Soda
  • Balloon
  • Funnel
  • Safety Goggles
  • Plastic Gloves

Safety Procedures

  • Be careful during the experiment.
  • Please listen to the safety rules before doing the experiment.
  • Please do not touch the vinegar, because if it goes in your eyes it will sting and burn.
  • Wear the safety goggles

Procedure:

1. Pour one cup of vinegar into the empty water bottle
2. Using a funnel, pour two tablespoons of baking soda into the balloon
3. Carefully, place the balloon on top of the mouth of the water bottle
4. Lift the balloon so that the baking soda falls into the water bottle
5. WATCH THE MAGIC!!!!!!!!!!!!!!!!!

Additional Note:
Make sure you have a table cloth, in case of any spills or mess.

The Science behind it:

Vinegar which is acidic ACID and baking soda which is sodium bicarbonate and is a BASE, when mixed together they produce carbon dioxide CO2 which is air and it expands the balloon that is attached to the water bottle.

​Conclusion:
In conclusion, we realized that the hypothesis was correct. The balloon did inflate.
