Vic the Viking - Season 1 Episode 2 Thor's Thunder

The drakkar runs aground on a reef in the fog! When they call for help, the Vikings only draw the attention of Sven and his men, who steal their cargo. Vic manages to recover the goods by making it appear like the pirates have been cursed. To do this, he uses bamboo sticks (bartered with a Chinese merchant during their last stop) that are actually filled in with gunpowder (kind of crafted firecrackers). These are loud enough to sound like the god Thor's thunder, and also explode with an unbelievable show of fireworks.
