Update #6

This is the last post for this project. We finished the experiment and concluded that bananas DO increase the gas production, and enhance the manure. We have prepared our posterboard, and are ready for tomorrow!

Experiment #2 (top view)

Experiment #2

Update #5

We are almost done with the project. We have proved that mashed bananas greatly increase the gas production by almost double, and the vegetable peelings were not available to us earlier, so we just used bananas and it worked out fine.

Update #4

We finished with test #1. We decided not to burn the gas in this experiment because we knew that only pure methane had collected. We guessed that there was some gas leaking from the balloon, so we reinforced the second bottle and made it more airtight. We emptied out the first experiment bottle, and disposed the manure. We began constructing the apparatus for the second experiment. For the second experiment, along with the manure, we are putting in mashed bananas and vegetable peelings. We are also going to at least test the gas to make sure that something has accumulated this time.

Procedure

Prepare Collection System

1. Gather copper tubing, vinyl tubing, large water bottle, ball valve, cork, balloon, and connectors.
2. Insert copper tubing into Mylar Balloon and tape down (make sure there aren't any leaks).
3. Drill T-Adapter into cork and glue tight (optional).
4. Attach ball valve to vinyl tubing on both sides.
5. Connect vinyl tubing to copper tubing, and attach the other end of the vinyl tubing to the ball valve, which would be attached to the burning apparatus.
6. Add manure(mandatory) + any other optional feedstocks.
