Green Project - 緑のプロジェクト

How do you disposed the engine oil bottle?

We are planning a green project at my son's school which called " Green Worm ". The school had dispatched note to all parents to invite them to join the project by giving away their used engine oil bottle regardless of color and shape. We found a very good example from a friend's website which will be our base model and it looks more or less like this photo. The green project will be held at 17 September 08 which is the school public holiday. Hope everything goes well! And most of all , we hope this event will bring up some awareness on recycling to the community!
