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

Hypothesis: (What do I think will happen)
I think the vinegar and baking soda will have the mst carbon dioxide.


Materials:

1. Vinegar
2.  balloons
3.  Sugar
4.  yeast
5.  warm water
6.  Bottle 

Steps:

1.  Put 1/3 Yeast in the bottle
2.  Put Sugar in the bottle
3.  Add warm water 
4. put the balloon over bottle
5. a half a cup of vinegar
6.  and some baking powder
7.  a cup of lemon juice  
8. And a tsp of salt.

My images:

Findings: I found out that baking soda and vinegar makes more carbon dioxide than any other.

	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)	12cm
Bubbles	NONE

Conclusion: Today in Science we had a Hypothesis about what makes more carbon dioxide baking soda and vinegar, lemon juice and salt and also Yeast and sugar.

On the first bottle Yeast one was the most unsuccessful
