Balloon Blowing With gases

 Aim: To see which mix creates the most gas.

Hypothesis: I think that all the balloons will blow up but I think the one with the sugar, yeast, and warm water will be slow and have the smallest effect, and I think that the vinegar and baking soda will be the fastest and have the biggest effect

Steps:

Balloon 1 

1. Put Baking Soda into a balloon using a funnel.

2. Pour vinegar into the bottle with a funnel.

3. Put balloon onto the bottle 

4. Hold down the balloon as it blows up.

Balloon 2

1. Add salt into the bottle Using a funnel 

2. pour Soda Water into the bottle using a funnel 

3. Put the balloon onto the bottle 

Balloon 3

1. Add yeast into the bottle by using a funnel 

2. Add sugar into the bottle using a funnel.

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)	10.6cm	5.5cm	5.1cm
Bubbles	Small Amount	Medium Amount	Large Amount

       

Conclusion:  At the end of this experiment Balloon 1 is the biggest by far and Balloon 3 is the smallest, in fact, it didn't even blow up at all it just stayed the way it was even though the yeast at the bottom of the bottle was rising a lot. When we added the baking soda to balloon 1 shot up straight away, but when we added water to the sugar and the yeast the ballon didn't budge but a few minutes later the brown yeast started foaming up, whereas the others started looking like lemonade.
