Experiment
Inflating a balloon!
What We Need:
vinegar
baking soda
a balloon
a funnel
an empty bottle
a teaspoon
Method:
1. Stretch open the top of the balloon and attached it to the end of the funnel.
2. Put two teaspoons of baking soda into the balloon, through the funnel.
3. In the empty bottle, pour in enough vinegar to half fill it.
4. Carefully holding the balloon so no baking soda tips out, stretch the balloon over the mouth of the
bottle.
5. Tip up the balloon so the baking soda falls into the bottle and mixes with the vinegar.
6. Watch the balloon inflate!
