I, however, tend to consider them toys which are played with at the bottom, not at the top. (At least not anywhere with lots of water and/or high drops. 1m falls on the Madawaska are fine at the top). According to Snopes.com, there's a lot people who disagree with me.
Apparently at the top of Victoria Falls there's a natural pool where people go play. Pictures show people basically sitting in the water, looking out over the edge of the falls and down. Honestly, they look quite believable . The only reason I'd doubt would be if these were some other falls, or maybe there's another pool a little ways down from here.
Either way, I'm NOT trying this one.
