Imagine you're hanging out on your boat having a coupla beers...

 

 And this crazy shit happens...

At least five people have died and nine were seriously injured 

after part of a canyon collapsed on top of tourist boats in a popular sightseeing spot in southeast Brazil Saturday afternoon. 

The dramatic footage above captured the moment a huge slice of the rock wall fell forward on top of two boats and sent waves and debris flying to a number of other vessels filled with screaming passengers. 

Authorities said at least 32 having been taken to hospital and nine are still recovering from serious injuries.
