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
Draw a pumpkin face on your balloon
Blow up the balloon a bit to stretch it out a bit
Use the funnel to add 2 tsps baking soda to the balloon
Fill the water bottle halfway with vinegar
Attach the balloon to the water bottle, make sure it’s a tight seal
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.
