A recycled rainbow?

At this week's Business Meeting the Eco Club representatives outlined their idea to recycle crisp bags and make them into a rainbow collage.
The children were asked not to crumple up their empty crisp bags and put them in  a specially marked bin at break time so that they could be collected to make the rainbow.
This could be the first rainbow ever that actually has a pot of golden wonder at the end!

Another two contributions to the Crispbag Rainbow.
