So the other day i was bored, and i decided to try and make a water bottle holder... i spent quite a lot of time making ones that all failed! apart from one, the simplest in fact
All you need to do is get a kitchen roll tube, and stab a hole in the area where you want the spout to come out and then put the bottle in!
i would only use it a temporary one as its not the best
(i am not actually using it by the way)
