In the experiment we discovered how to blow up a balloon without using our breath!
The things we needed were...
Baking soda
White vinegar
A fizzy drink bottle
A spoon
A funnel
A balloon
Measuring cup
This is how we made it...
First we put the balloon on the funnel. We poured 2 spoonfuls of the baking soda into the balloon. We took the balloon off the funnel and put the funnel into the bottle. Next we poured white vinegar into the bottle. We put the balloon full of baking soda onto the neck of the bottle and.....
the balloon blew up!
