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.
