watering your cham?

[choriona]

I was just wondering how everyone goes about making sure their cham is drinking enough. Personally, I have water fountains in each of my cages and I've hardly observed the use of them, but I know they must.
Also, I have a few of those sport water bottles that you have to squeeze to get water out - then I hold onto the cham with thier heads facing the sky and let the drips run down their noses and lips. Usually they start drinking in no time. My gravid females especially enjoy this.
My panther gets a drip container - which makes me angry because sometimes it dosen't drip. (Any suggestions? Its a zip-loc container with a pin-prick in the bottom side edge and i keep the lid off.)
I have also heard of people using ice cubes on the top of the cage that melt and drip into the enclosure.
Or do some people just rely on spraying/misting?
