Vinegar, Baking Soda, and a Balloon!

For this experiment you need a few things. 
1. Baking Soda
2. Vinegar
3. 20 oz pop bottle
4. Spoon
5. Funnel 
6. Balloon
7. Clothes Pin  

First you, fill the balloon with about 2 spoon fulls of baking soda, use the funnel to get it in the balloon. When done, clamp it securely   with the clothes pin, so the soda does not come out. 

Next, fill the pop bottle with vinegar to about half way between the bottom and the label. 

Put the 'sealed' balloon on top of the bottle. 

When you have it on securely, flip upside down and remove pin. Shake baking soda in to the bottle. 

When all the baking soda is in with the vinegar let go and stand back and watch!
