So I built the base of a stream/river on some wood, I used some wood filler to make the banks, then, I painted it sealed it with Mod Podge and used some clear elmers glue to try and make a nice clear stream/river, but after 3 days the thing dried horribly. So I'm looking for some advice on how to make a clear stream, what I can use to make a body of water that won't dry and flatten out or get huge air pockets in it.
