The soaking in a bucket lets you see how it'll hold together, just to make sure the silicone cured correctly.
I started to silicone my Slate cave, but my poor silicone skills meant it fell apart on me after putting it in.
So, I decided to make my cave without silicone and just let the weight and friction hold it together. It works because my cave is two levels tall.
Make sure to post some pics!
