Aim: To see which chemical 
the mix creates the most gas.

Hypothesis: baking soda and vinegar 


Materials:

1.  3 Balloons
2. 3 bottles
3.   3 tsp baking soda,
4.  ½ cup vinegar
5.  3 tsp salt,
6.  ½ cup soda
7.  2 tsp yeast, 
8. 1 tsp sugar 
9. funnel
10. warm water

Steps:

1.  put all the liquid ingredients into the bottom of the funnel
2.  put all the solid ingredients into the balloon
3. quickly put the balloon on top of a bottle
4.  wait 20 minutes and measurer in cm.
5.  put information on the graph

My images:

Findings: baking soda and vinegar 

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	20cm	6/2cm	13cm
Bubbles	a few	a few	heaps

Conclusion: I found the baking soda and vinegar raised the most. the yeast and sugar rises of the slowest. the last thing I learned is that all these mixtures release carbon dioxide
