transformers part 2

A nifty idea for protecting seedlings from strong winds - just find a wide-necked bottle, cut the base off, cover the seedling and push the screw-end into the ground.

Can be removed from the ground when the seedling begins to grow.




I have seen a similar idea online, although it used the plastic bottle to direct weedkiller to an isolated weed, protecting the rest of the lawn/plants from the harmful chemicals.

The process to transform the plastic bottle into the concept above requires a simple cut with a knife or a pair of scissors. One problem associated with second life design is the finish on home-made objects. Because they have not been industrially manufactured, if you make 10 of the same object, they will all be slightly different.



The sketch above coveys the dilemma - each time I cut a bottle, the finish will be slightly different. Is there a way I can make sure every cut and every finish is exactly the same?

Answering this question may provide a solution to the lack of openness towards second-life design...
