Try a Scottish Bap.
I bought 4 for £1 this morning.
They are False, Fake and Phoney but eldest LOVES them.
I’ve travelled across the Forth Rail Bridge and the Forth Road Bridge many times.
Whenever we took a train over the rail bridge it was custom to throw a penny out of the window. To REAL Scots, that is.
Travellers on trains crossing the Forth Rail Bridge would throw coins out of the carriage windows for good luck.
It’s like painting the Forth Bridge is a well-known saying.
As in…by the time you’ve finished, you are forced to start again. Much like Sisyphus (?)
