Construction

We created a list of everything we would need and volunteered to bring in different items, to make things easier we wrote the list on our google doc; which is our homebase for storing information and collaborating.

We used:
1) a 2 liter pop bottle with cap
2) 1 cup of sugar
3) 1 tablespoon of yeast
4) & 6 cups of water
5) Silicon airline tuning
6) Hot glue
7) Pressure valves

To make the solution we had to pour six cups of water into the bottle and add the yeast and sugar. Afterwards we shook the bottle to mix everything together. It took a few hours to build enough pressure to force the gas into the tank. We drilled a hole into the cap and fed the tubing through, we hot glued both sides to keep the gas from leaking and attached the pressure valves to the middle section and end.

This is what it looked like:
