Help! Water bottle running dry

Question
I am the proud new parent of 3 dumbo males :)  I am however, having problems with their water bottle. It is a "critter canteen." I've followed the instructions as best I can. Fill the bottle completely and hang it upside down, but it is drying out with plenty of water left! It's like they drink what's in the metal tube, but then it stops flowing entirely. I've ordered a high quality "Edstrom's Water Buddy" but it won't be here for a week. Any suggestions?

Answer
Well, I would recommend you take a trip to walmart and buy a cheapy 88 cent water bottle to hold them over till the new one arrives. And if your super desperate, a water bowl that is very heavy ceramic.. But this will get VERY messy very fast and will need to be replaced several times a day, and some of them may not even know to drink from it... Good luck!
