The Daily Mail is especially hated because it's a tabloid hiding under a veneer of respectability. It has a long history of pandering 'science' stories.

This story for example. Don't you wonder how the interior of the glass has stayed so spotless for 40 years? It has to be cleaned, but they don't explain how.

Maybe it's some kind of magnetic cleaner, or maybe he's simply opening the bottle up to clean it. It's an obvious question, but it's typical of the Daily Mail's cynical and patronizing attitude that they don't care to answer it.

Cleaned from what exactly?

Post science not speculation.

From The New York Times Garden Book:

...clear glass encourages the growth of algae...

The bottle garden should be cleaned inside and out once a month.

Algae growth tends to be rapid in bottle gardens... This monthly scrubbing and cleaning out is the key to the whole success story.

Just seen this - nice links.

It seems the story is indeed disingenuous. Thanks for posting.
