The hallowed art of building a maritime model in a bottle is nothing to laugh about. It requires a good eye, a precise touch and steady hands – with a ton of patience added onto that. There are various kits you can get to build your own and even websites to help you. You could even join on of the world-wide associations such as the SIBAA. Ship-in-a-bottle day is on the same day as Taco Day and Vodka Day – it could be interesting to combine them all, but you might want to hold off the spirits until after your ship has gone in.
