Thanks guys!

I was wondering if it would be possible to run tubes to some of these bottles to keep them full.

It's likely that it might be cheaper to just get nozzles, but I feel like I could get more water in that way?

Really I'd like to see if I can find a ball nozzle like those you find in most small animal bottles.
