NOT a good idea.

1000+ Reddit comments: http://reddit.com/r/videos/comments/...     

I still don't totally believe this video, it seems like way too high a height, I think the film has been doctored.  

There is much debate on the Reddit page about whether it's real.

The pool is only 5 feet deep. Seems fake, I mean this is how Anthony Kiedis broke his back.

From Anthony Kiedis' Wikipedia page:

Kiedis and Flea began jumping into swimming pools from buildings as a hobby. At age fifteen, Kiedis broke his back attempting to jump into a swimming pool from a five-story building, missing the pool by a few inches. His back has since improved, although he still has occasional problems.

Reddit explains but does not excuse!

It takes very little water to sustain a landing from that height. I mean yeah, 5 feet is probably about that limit, but it's not like you'll pancake in the pool bottom. It'd be like jumping 10 feet onto the ground. It's a stiff landing but a little water goes a long way.

Plus, you'll go right to the bottom if you hump jump head or foot first, but he kind of cannonballed, so he didn't dogo as deep.

Still, what a dumb, dumb thing to do.

Reminds me of Bugs Bunny high diving into a glass of water.
