UGLY BAGS OF MOSTLY WATER

I need to get this down before it vanishes: I had a dream last night that while battling robots and agents of some evil human organization, I invented a disintegrator cannon. It worked fine on the robots, but while being pursued by the agents, I fired it at a ziploc bag filled with water, and it only made the bag puff out temporarily before returning to its normal shape. Sure enough, when I shot the humans, it had the same (weird-looking) effect, distorting them grotesquely for about half a second but not doing any real damage. I guess it didn't work very well on anything that was essentially a sack of fluid? Future weapon designers, take note.
