Video: When the Super Soaker was released 25 years ago, it stirred up a bit of controversy when some idiots filled the water guns with bleach. But that's nothing compared to how dangerous this pressurised water gun that YouTuber Asp built. It's capable of inflicting a tremendous amount of damage, even serious bodily harm if pointed in the wrong direction.
If you've ever tried to break a CD with your bare hands, you know they're designed to endure a lot of punishment. But this water cannon instantly shatters one into hundreds of tiny shards. Imagine being on the wrong end of that during a water gun fight. That's one duel you'll want to forfeit.
