There's a magic ring in a sealed paint can at the bottom of a frozen pond in the middle of a bog. YOu must get the ring via a plan which: gets you and equipment you need across without sinking, cross the frozen pond without breaking through the ice, lift the paint can out of the pond - it weighs 50 kg, get the lid off, snatch the ring and escape!!
