Bubbles...

... you're doing it wrong...

Not the best confetti shot in the world, but could easily have ended up on one of those "seconds from disaster" tumblr pages. Look on the top left-hand side of the photo and you'll see two small plastic tubes of bubbles, which were handed out at the same time as the confetti. Obviously you're supposed to blow the bubbles, not fling them at full speed at the bride and groom's heads like missiles... thankfully nobody lost an eye.
