Science writing

when you mix warm water with sugar and yeast it makes the yeast 
multiple and creates carbon dioxide witch is a gas. The carbon dioxide fills the balloon with air we use yeast in our real lives when we make bread then we put it in a warm place. And then wait for it to puff up then bake it the yeast dies when it's all the way puffed up it leaves holes.

When Toby put the balloon on with the 

baking soda the vinegar shot up in to the balloon

along with the bubbles and carbon dioxide

the chemical reaction made the balloon

get really fat because of the carbon 

dioxide that made presser but it did 

not burst.
