Water Bottle Rocket Fail

Now this is one of the coolest inventions ever! It's a jetpack that runs entirely on water!

Did these guys actually think it would be successful? Poor guy didn't even see it coming.

This guy pulls off the old bottle rocket prank on his roommate while he took a shower. That was a classic!

That's probably not the only thing he takes to the face.

When your bottle rocket doesn't go off as planned, make sure you keep the exploding part away from your nuts when you go to inspect it.

The result of a homemade bottle rocket gone wrong! I also have to say that the cameraman's laugh is probably the most annoying ever.

Do not try this at home... for obvious reasons!

Those crazy Japs have done it again! They somehow turn a bunch of water bottles into a homemade jetpack and it actually works too! Watch this awesome invention in action...

Fail!!!! :(:(:(:(:(

Another reason you just have to love live TV. I'm guessing this guy had the perfect take off in mind, unfortunately his jet pack didn't feel the same way!

This is what happens when a third world country tries launching a mortar rocket. Didn't get the kind of distance they predicted.

Sometimes greater things can come out of failure. In this case good footage got even better after this water skier wiped out.

Teen pop star Justin Bieber gets nailed in the head after someone in the crowd launched a water bottle straight at him. Pretty good accuracy!
