Speaking of bottles, My daughter Maddy got a boat-in-a-bottle kit for Christmas, from a friend at Dalhousie University in Nova Scotia, where she is a student. We tried to build it together over the holiday break.
It's fiddly fiddly work, as you may well imagine.
'Thinking hands' are sometimes not as bright as what you need for the task at hand.
But anyway we got it done and we are still friends, though I suspect she may not feel as kindly towards the person who gave her such a finicky, spatially challenging gift.
I wondered if building a wall in a bottle might be less difficult, so I tried it.
