Don't have a raking tube or tubing? No problem as long as you're using a 2 liter (0.5 US gal) bottle for secondary fermentation. All you need is about 6 "Bendy Straws", and the cap to the 2 liter (0.5 US gal) Soda bottle. Take 2 of the straws and attach them short end to long end. Take 2 of the remaining straws and cut them leaving about an inch on each end of the bend. Connect those together and to the other straws. Here is your raking tube and "hose". Now put 2 holes in the soda bottle cap just big enough to fit the straws stick the single straw end (not the end with the short straws) and stick it through the top of the cap. Now take you last straw put it in the other hole. Now once primary fermentation is complete and you want to transfer put the cap with the straws on your primary fermenter stick the "Racking tube hose" in your secondary and blow into the primary via the other straw and as long as you have no leaks in your "raking tube" straws you will create a slow but effective siphon.
