Re: the firefly effect
on sailboats the sails and rigging are held up by shackles. Little U shaped fastners with a bolt that closes one end.
One of the tricks sailers play on noobs in their first race: at the start of the race you toss an open shackle onto the deck of the boat next to you.
The skipper thinks it fell off his mast or rigging, and stops to figure out where it came from. If you really lost a shackle from your rigging then either your sails, or you mast would come down.
