Ive actually been doing this for some time now, never thought to share, thought it was kinda primitive. oh wel learn someting new every day. also, what i do, and in respect to the video, i add a thin layer of sand to the bottom of the container, so if the glue does drip through its even easier to remove, also, i sprinkle some fine sand on it before i compress it, fills in all the gaps.
