 Title:Inflating balloon
 To do this experiment we needed:

•  Paper funnel
•   Bottle  
• Balloon 
•  Spoon  
• Vinegar

How to do this experiment 
 First we put vinegar into the empty bottle. 
 Next we used a paper funnel to put the baking soda inside the balloon. 
 Then we put the balloon on the mouth of the bottle. 
 Next we shook all of the baking soda out of the balloon into the bottle.
