DescriptionSundial cannon clock 2.JPG	English: This is what’s called a sundial cannon, or a noon cannon , assuming the weather cooperates, at noon exactly the lens on the sundial focuses sunlight onto a pan filled with gunpowder, setting off the cannon to mark the time , generally, the cannons weren’t loaded with shot, but with all of the novelty alarm clocks out there, it seems like one that automatically shoots you could be really, really effective, in a potentially dangerous sort of way , at the Queen`s Terrace at the Palácio da Pena palace, Portugal Македонски: Топовски пладневен сончев часовник работи на принцип да на пладне точно на објективот на Сончевиот часовник фокусира сончевите зраци врз тава полна со барут и се активира и означува пладне , примерок од кралската тераса во Пена дворецот во Синтра , Португалија English: Sundial cannon clock
