Compressing Biogas into BBQ bottle

Trials and tribulations of compressing biogas, had to film this over several days due to set backs and no time due to work but, we got there in the end. I apologise for the sound with all the rustling and pops etc, certainly not a cinematographer but i will see how i can rectify this. Stay tuned for more videos, subscribe, comment, im happy to answer questions where i can.
