David gave me instructions on how to gas the beer! mmmmmmmmmmmm. He said there was a release valve and it would stop taking in gas.
This is the picture I took when I realised the barrel had changed shape. I had previously been covered from head to foot in beer, because when I first started to gas up, the tap was open!
You have never seen me run so fast when the release valve eventually went off. The noise was like a high pitch whistle, I thought the thing was going to blow up.......
