Carbonerific?

I've never been all that happy about the lack of fizz in my ginger beer. Having said that I don't fancy investing in a Soda Stream or some other sort of carbonation equipment (not at this stage anyway.) A search on the internet suggests that there are a few options available to me to get the bubbles so I pick this one and get underway.  I have everything I need except for the plastic tubing but a quick trip to Bunnings fixes that. I drill some holes, stuff the tube in, get my vinegar and baking soda measured out. It is a careful pour to get the ginger beer from the brewing bottle into the carbonating bottle, because I don't want the sediment all getting mixed in by the bubbles. It is then a case of putting the tube into the ginger beer, screwing on the lid, tipping the baking soda into the vinegar bottle and getting my shake on. Unfortunately without seals around where the tube goes through the bottle lids a fair amount of the vinegar seemed to be coming out too. It also looked like it might have been traveling down the tube and into the ginger beer....Not sure that that would improve the taste. The tube bubbled away nicely for a while and then eventually I pulled it out and let the foam on top of the ginger beer settle. It poured nicely into the glass and there were certainly bubbles in the ginger beer. It probably did improve the taste to have the bubbles in the drink, but if I have to go to that much more effort every time I want the ginger beer to be bubbly it might be easier just to buy some...oh well, back to the drawing board.
