About 25 years ago I purchased a bottle of Harrogate Spa Water.
When it was nearly empty I decided to test out the principles of homeopathy - which claims that the properties of something are preserved when you dilute it. so when the bottle was nearly empty I topped it up with tap water and put the bottle back in the fridge. If homeopathy is true the contents are still effectively Harrogate Spa Water - as it clearly still said on the label.
Nearly every night since then I have taken the bottle from the fridge and poured a glass of cold Harrogate Spa Water for a final drink before I go to bed.- topping the bottle up every time it is nearly empty.
So far the water has been diluted 10-fold on about a thousand occasions and I guess that not one of the original molecules of Harrogate Water remains in the bottle - but each night I still enjoy a lovely cool drink. By now not one atom of the original contents remain ...
Perhaps I should write a review saying how wonderful Harrogate Spa Water is and how its excellence has lasted 25 years - and perhaps my review would be republished as a recommendation from a satisfied customer in an advert .
But wait. The label is starting to disintegrate. Perhaps the bottle is embarrassed and is trying to tell me that homeopathy does not work, and it no longer wants to be seen carrying a misleading "Harrogate Spa" label.
But do I care what the bottle thinks about the effectiveness of homeopathy? Of course not. By repeatedly diluting the original water I have avoided having to throw away 999 plastic bottles (and saved myself a lot of money).
So if you want to help save the planet may I suggest that everyone should start drinking homeopathic water - just buy one bottle and keep it topped up from the tap.
