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

Hypothesis: (What do I think will happen)
I thought that the gas would make the balloon grow really big and that the liquid would rise a lot.
Materials:

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

Steps:

1.  grab the bottle make sure it's empty and dry
2.  grab your funnel and balloon
3.  Get the first ingredients 
4.  Pour 2 tsp of the yeast and 1 tsp of sugar, make sure to pour it in one at a time.
5.  Then wait for it to rise.
6.  for the next experiment do the same thing with the salt and baking soda for the other 2 ingredients 

My images:

Findings:

	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)	12.5cm	5.2cm	4.5cm
Bubbles	a small number of bubbles	medium about of bubbles	a large number of bubbles

Conclusion: What have I learned from my experiment. The mixture of baking soda and vinegar makes a reaction to each other creating more gas than most other mixes. The mixture of salt and normal soda makes the little amount of gas compared to the baking soda and vinegar. In conclusion, if u want to create more gas I would recommend baking soda and vinegar.
