What if water did have memory? What if water somehow "remembered" everything that had been in it, once upon a time? Water is recycled - your glass of water has been rain, river, ocean, pond scum, cow piss, bug poo and dinosaur blood. Firstly wouldn't we'd have noticed by now if the provenance of a particular piece of water (say, lake water vs. rainwater) made it behave differently? And secondly what measures do homoeopaths take to cancel prior "memories" in the water that they use? Homoeopathy is not only false, it doesn't even make consistent sense in it's own terms.
