Cow Manure Methane Gas

Postby hanupoci » Sun Aug 01, 2021 11:30 pm

my project is similar to the "From Trash to Gas" biomass project on here, where I fill three 2 liter bottles with cow manure, three with cow manure and vegetable peelings, three with cow manure and corn stalks, and three with cow manure and salt. All of them have water added to them. I had taped balloons to the neck of the bottle, and expected them to blow up after a week or so. At first, two of the vegetable peeling bottles blew up a little, but immediately deflated after two or three days. I've waited three weeks now, and they are all completely deflated now. Can someone help me? Thank you!
