I cannot tell if it's photochopped or not but most certainly CRAZY.

Impossible.

Mythbuster busted this myth. Even if they could get enough blasted to make a wave the shock from the blast could kill them in water.

They did this on mythbuster.

^^^Ditto^^^  I also saw it on myth busters

yup saw the episode of mythbusters too. it was a good episode. you can pretty much tell its photoshopped cuz the lighting on the explosion doesnt look like the rest of the lighting.

Children should NOT be allowed to play with firecrackers  

Photoshopped or not that was cool. lol

that would be pretty sweet to do that!!!! but def impossible!!!
