Finding forms in cartons

I spent some time chopping up my recycling to see what can be simply made from milk and juice cartons made from this type of laminated cardboard, sometimes with a layer of aluminium.

Beverage cartons that hold juice, milk and liquid foods are made from a laminated combination of card, plastic and often aluminium eg brand names TetraPak and SIG. Not so environmentally friendly, but great to work with. What can you do with a carton?
