After a birthday party of things to recycle there are several, among them invariably a few bottles of Coca Cola. Here are some of the photos taken by during processing that follow that idea.
The bottle of Coca Cola has 10 channels, through making 5 cuts of about 5.5 cm along the grooves themselves, cutting a groove and is a no. Round off the edges, in the pictures I've highlighted with a marker lines to follow but it is only to make you understand better, the pen really should not be used because it would then removed.
Fold down the 'fins' and you're done! Filled with what you want and finished with a ribbon.
The red Christmas ball that you see behind was filled by recycling an old wire Christmas tree while the blue one I used chips made from a water.
