Halloween Balloon Experiment

Materials

• Baking soda

• Vinegar

• Empty water bottle

• Orange or white balloon

• Black marker

• Measuring spoon

• Funnel (optional but helpful, we like this one)

Directions

1. Draw a pumpkin face on your balloon

2.  Blow up the balloon a bit to stretch it out a bit

3. Use the funnel to add 2 tsps baking soda to the balloon

4. Fill the water bottle halfway with vinegar

5. Attach the balloon to the water bottle, make sure it’s a tight seal

6. Lift up the balloon to dump the baking soda into the container of vinegar. Watch the balloon fill up!

What’s Happening?
The science, behind this balloon baking soda experiment, is the chemical reaction between the base {baking soda} and the acid {vinegar}. When the two ingredients combine, the balloon expands.
