Hurumanu - Balloon chemistry

Hurumanu - Balloon chemistry

Aim: To see which chemical 
mix creates the most gas to blow up the balloon.

Hypothesis: From the start I had no clue what was going to happen because i don't really have experience with chemical.

Materials:

1. 1 spoon of sugar 
2.  2 spoons of yest
3.  balloon x3
4.  funnel
5.  hot water
6.  3 spoons of salt
7. 3 spoons of baking soda
8. half a cup of vinegar
9. half a cup of soda
10. 
    

Steps:

1. Get your bottle and put all your ingredients in using a funnel
2. poor hot water in. 
3. Then quickly put your balloon on the lip of the bottle. 
4. now wait for the magic to happen

My images:

Findings: I found out today that baking soda and vinegar blew the balloon up bigger and faster.

	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 cm	9 cm	10 cm
Bubbles	Lots of bubbles		Not much bubbles

Conclusion: 
When the yeast and sugar were mixed together it was going very slow and from there I knew it wasn't going to go very far. In the end it blew up 10 cm I thought it was going to at lest get over 20.

Next was the salt soda at first It was going like medium speed I thought it would be the biggest. But after about 3 seconds it just stooped. It manged to retch 9 cm.   

Last it was the baking soda and vinegar, it started off fast there I knew it was going to be the biggest after about 10 to 15 seconds it stooped. It got 12 cm
