Balloon Science

April 29, 2020

 

Have you ever tried this variation on the baking soda and vinegar balloon experiment?  It is so easy to do, and it really is exciting to watch. The reaction between the baking soda and vinegar cause the balloon to inflate all on its own. The kids will love it. It is so easy to do, and it really is exciting to watch. This is really a perfect science project for kids to try on their own.

 

Please Remember: Balloons are a choking hazard for young children. Keep a close eye on any balloons used.

 

 

 

Supplies you will need for the experiment:

  • balloon

  • vinegar

  • baking soda

  • funnel

  • spoon

  • empty water bottle

 

 

 

 

 

 

 

 

 

Directions

 

 

 

 

Step 1. Pour 1–2 inches (2.5–5 cm) of vinegar into the empty water bottle.

 

 

 

 

 

 

 

 

 

 

 

 

 

Step 2. Before pouring baking soda into the balloon, you will need to stretch out the balloon to make it more loose and easier to inflate. After that, pour 2-3 spoons of baking soda into the opening of the balloon, using a funnel. You will need to shake it a bit to get it down into the base of the balloon.

 

Step 3. Stretch the opening of the balloon over the top of the bottle leaving it hanging down until you are ready for the reaction. Be careful not to spill the baking soda while you do this.

 

Step 4. When you are ready to see the chemical reaction happen, lift the balloon up over the bottle and watch the reaction. The baking soda should fall out of the balloon, through the neck of the bottle, and into the vinegar at the bottom.
