Ideas from school kids

I recently gave a talk at junior high in the Finnish city of Kokkola (which is located on the same lattitude as Nuuk, the capital of Greenland). I asked them if they had any ideas, and among the more useful ones were these:

A stoker, the kind you use to move pieces of burning wood in a fireplace. A nice suggestion methinks, very symbolic somehow.

A sword hilt with the blade removed. I can't understand how we missed this one!
