Presence of sugar in the both bottles
Yeast of course, beer bottle, water, balloon and sugar maple syrup.
The sugar is needed as food for the yeast. The yeast gives off carbon dioxide as it digests the sugar. The carbon dioxide could be used to inflate the balloon. Without the sugar, the yeast remains dormant and does not give off carbon dioxide.
the balloon will inflate
Yes this can be done but the process would be really slow. You can try adding some yeast to hydrogen peroxide and let the balloon be tied to the bottle containing that mixture. After couple of hours you will have inflated balloon.
physical change
Yeast of course, beer bottle, water, balloon and sugar maple syrup.
It does NOT produce CO2
Personally. the yeast in the balloon experiment would be more interesting.
you did not answer my question . please answer the question I give you I said the hypothesis about how to make a ballon blow up using soda and yeast
The independent variable is the type of liquid you mix with the yeast and the dependent variable is how big the balloon gets.
Experiment
Yes.
Live yeast can be used to inflate a balloon if you give the yeast something to ferment (such as sugar). They then produce carbon dioxide as a waste product that could inflate a balloon. You should not expect it to be buoyant, however, for CO2 is heavy as gases go (considerably heavier than air, for instance). The yeast cannot use salt for much of anything, however.
To look good
Yes, a candle can power up a hot air balloon. But you need a mini one to do the experiment. search hot air balloon experiment on Youtube for videos.

first u can take a plastic bottle put two spoons of suger,three small spoons of east and put some hot water in it and then put a balloon on the bottlel's mouth then just wait and watch the all carbon dioxide go into the balloon slowly slowly
