Out gassing water and glop

I wanted to see how long it took the water I had on hand to outgas. The bubbles did not rise to the top. They gathered on the walls of the water bottle. Is that what it is supposed to do? Do I just stir to get the bubbles to rise or will that cause problems? When I have pigmented glop how do I know when the glop has sufficiently out gassed since the bubbles attach to the side of the bottle instead of rise? Sorry if these are dumb questions.

Has your out-gassing experiment only been done with a bottle of water?

I don't think you're going to have any problems if you make up a gelatin/pigment glop; I always make mine in glass jars and I've never seen any kind of bubbles attaching to the sides and very few on top even.

Unless you're having problems with glop actually, I hate to say it... but I think you might be over-thinking this. (usually I would never say this, because I hear it all the time myself!)
