It's been a while since I visited the HADO site, the wonderful world of Water. Dr Emoto discovered that the same samples of water behaved very differently when they had different words written on them. Sample of water from different places showed different results too.
There is a video about the preparation of samples of water, pictures of frozen water crystals, but most interestingly, a page of links to articles which show how "love" anbd "demon" written on a bottle of water changes its crystalline form.
I don't know what's going on, or what the research shows, but I find the results fascinating and beautiful.
