Sundial Cannon Could Be Most Effective Alarm Clock In History

Sundial Cannon Could Be Most Effective Alarm Clock In History

noon-cannon

By Evan Ackerman

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. And hey, it’s even solar powered.
