Balloon chemistry

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

Hypothesis: (What do I think will happen)
I think that all the gas will create a chemical and it reacts into a gas called helium.  

Conclusion:
What I have found out from making the gas's is that the salt gas/reaction to it. It doesn't work.    

Materials:

1. Bottles
2. Balloon 
3. Soda water
4. Salt
5. Baking soda
6. Vinegar

Steps:

1.  Put baking soda in one balloon 
2.  Then put vinegar in the bottle
3.  Pour the baking soda into the bottle
4.  Put vinegar in a bottle  
5.  Put the salt in
6.  Put the balloon on the neck of the bottle
