Message in a bottle!

No 2 son is getting married  at the end of April to his partner of 20 years.
The invitation has arrived folded up in a 2" high bottle.  An extra copy of the invite is also supplied to save using tweezers and risking spilling the glitter powder too.
The wedding is a small family affair, miles away in Clovelly on a clifftop. (this is the son who held his 50th birthday in a nuclear bunker).  It was only announced after I had booked a holiday in Corfu. I will be returning from that holiday and whizzing down to Devon the next day.  He never does things by halves.
