Think inside the box!
Have you ever considered that the world around you is full of 
containers, in all possible shapes and sizes? Many of those 
you see can in fact fit inside something else!
They are made from a world of materials.
Wood, clay, leather, stone and reeds were the first to 
be used. Later came paper, glass, china, rubber and 
plastic. Some containers are hard, some are soft. Some 
are transparent, some are opaque. Some are light, some 
are heavy. Some are strong, while some rather flimsy.
