Gardening Ideas at the Ideal Home Show

Gardeners weren't left out from the ideas shortlisted for the Innovations section of the Ideal Home Show recently. First up was an idea to save watering can overflow. I'm forever off to fit in another quick task whilst my can's filling up, only to return to find I'm also watering the patio. I won't attempt to explain how it works, but you can click on the image to enlarge it if you feel like reading the blurb...

Those of us used to using springform cake tins will be kicking ourselves for not applying the same principle to the humble plant pot - would we be millionaires by now? Maybe, maybe not...

Finally, not strictly speaking a gardening idea, but it gets to the heart of solving many a gardening tea break disaster. I suspect Nicey and Wifey might have a word or two to say on the subject...
What do you think of these ideas? Do you think any of them will actually hit the shops? Have you got an idea of your own? If so, perhaps you need to enter next year's competition...

Update: Crumbs, Nicey and Wifey had more than a word or two to say on the subject - do have a look here. And a warm welcome to those of you who've come over from their lovely site.
