Summertime is imminent, and you know what that means: water balloon wars. If you want to dominate the competition and soak people from afar, you can't really go wrong with the Water Mortar. It takes what was once a friendly backyard game and turns it into something much more serious.
Mounting on your shoulder, you should strike fear into the hears of your opponents before you even start firing. Once you start firing? Look out. With a range of 15 to 20 feet, it won't be too tough for them to run away, but getting a hit within that range is sure to be some sort of satisfying. Sure, it might be an unfair advantage, and it'll be considerably less fun for the people you're playing with, but who cares? This isn't fun and games; it's war.
