Ever see that footage of the home made liquid explosive device that government scientists made during the trial of the airline bomb plotters?

Remember the shock wave coming from it , visible in the slo-mo? That's what would hit you, only in the water, which is much more dense than air, and so would couple effectively to your body and transfer more energy to it.

The water itself is not moving in bulk, hence the -static bit - it's just a shock wave caused by microscopic motion of the water molecules transferring energy to each other very quickly.
