We're sure it's fun to simply build and fire a massive cannon but wouldn't it be better to see what happens after the cannonball is shot? This 7th-grade girl decided to do just that for a science fair project. She and her father wanted to test to see how high the cannonball would go so they ...

We don't know about you, but getting us to base jump would be a near impossible task. Ad fog to the mix and you'd have a better chance of getting us to take up knitting over a fishing trip — not gonna happen. GoPro athlete Marshall Miller apparently has zero fear of anything as he base jumps ...

You might remember Rush Sturges and Ben Marr as the two kayakers who said the heck with the water and rode down a drainage ditch. Well, they're back again, only this time they teamed up for the ride in a tandem kayak. Watch as they return to the ditch and take it on in an attempt that's the ...

Who needs a parachute to go skydiving when you can just float doawn with a giant umbrella, Mary Poppins style?
