Further milk bottle recycling

I have had so much use out of recycling our plastic milk bottles (http://ecofootprintsa.blogspot.com/2010/10/recycling-and-storing-tip.html) that I couldn't help but wonder what other uses the bottle could be put to.

Well, this is my latest one...

I am going to use them to grow upside down tomatoes, peppers, peas and beans in.  That way it'll save on having to buy hanging baskets with coir liners(which the dratted starlings are shredding as bedding for their nests) and, as the bottles are see through, I can also clearly see when the soil needs another gulp of water.

What I did was this -  about 2 1/2 cms (1 ") below the lid I cut open and removed the front top half of the bottle, leaving the back half of the bottle to support the neck.  I also punched two holes in the base for drainage.

Then I tied some twine around the neck, planted it up, and hung it where, in this instance, the tomato plant will get the morning sun, but will be in the shade during the hot afternoons.  A raised bed with a difference :-)  And I wont have to tie up the tomato plants on a stake as they grow - they'll grow down towards the ground which will make them much easier to harvest.

I guess one could also use this idea in a workshop for holding nuts and bolts, screws, nails, etc. Or clothes pegs. Or next to a childs desk to hold their pens and pencils.

But for me - any extra year round sunny garden space is a bonus - even if it is 1.5 mtrs (5') above the ground!  So I've also cut out two (opposite) top sections, with the area in between the spaces being the support for the neck, and the open areas allowing me access to harvest the fruit - perfect as a strawberry pot?  Time will tell...

All I have to do now is cut off the two flaps and
there we go - instant hanging strawberry pot

Has anyone got any other ideas?
