Where would you stick this bottle?

A few years ago, a Japanese company designed a bottle that could be stuck in sand. Now I've never personally had a problem sticking stuff in sand because, well, it's just sand.

The problem is if you don't have sand to stick it in, it'll tip over. So right now in whatever room you're in, what would you stick this bottle in?
