Hi! I saw a forum thread some years ago on how to make water effect using toilet paper and glue. I have tested this method and was very happy with the result, so I made a short video showing how itīs done. See link below.

I think this method is close to "fool-proof" in getting a good and realistic result. Itīs also obviously a very low cost method, so I thought it was a good idea to spread this method by making a video tutorial. I hope you like it.
