Remember those hot, summer days back when you were a kid, throwing water balloons back and forth with your friends?

If you happened to drop it or catch it in the wrong part of your hand a splash of water no more than a cup full would get on your clothes. Not a big deal at all.

Well Gav and Dan, aka The Slo Mo Guys, give "exploding water balloons" a whole new meaning with their latest video and it's definitely a BIG deal. You might need to put on a wetsuit to watch this one.

Now that's how you spend a beautiful afternoon in the middle of summer. Check out some other videos from The Slow Mo Guys on their YouTube channel.
