We watched a video of a family (well, two adults and two kids) being swept away by a flash flood into a waterfall and dying, it was HORRIFIC. I singed up for that class as an easy way to pass my science requirement and they show us the most disturbing video I have ever seen, you could hear the people on the shore screaming and yelling and crying, it was traumatizing. At first the family were just standing in the water happily with very very low current, and the out of nowhere a massive amount of water comes and they stay put thinking they can ride it out, but eventually they are swept away and fall into the waterfall to their deaths
