It can be transparent or brightly coloured. It's beautiful.
You can use it to make almost any household object you need- maybe not blades but just about anything else...
And it's cheap.
The problem isn't with the product itself but with our disrespect for it.
Because it's cheap we use it once and dump it- and no-one these days has any excuse for not knowing the problems that causes.
So don't dump, recycle...
Or even better- because some recycling companies think recycling means moving things to India and dumping them there- re-use.
Here's an idea for re-use that Ailz found online.
You cut a plastic bottle in half, invert the top half inside the bottom half, fill the bottom half with water and the top half with soil- and you've got a planter you don't need to be watering all the time.
I've only just made the example in the picture so I can't honestly say that it works, but I don't see why it shouldn't.
The coriander plant is a bit droopy- but that's why it needed replanting....
