I love what you've done with that overflow. How did you actually attach it so the whole thing just doesn't topple over? What is that foam stuff you used? I've seen other people do similar things with it. I'm thinking of doing something similar but finding it over here...Can you take a picture of teh can so I can show it to my my father-in-law - then I can cart him down to the hardware store to find it.
And what do you use to stick the sand on?
