When gannet chicks are fully grown the parents abandon the nest and chick; a few days later, when the chick realises the food supply has dried up, it launches itself of the cliff face, perhaps 200 feet, into the sea below. It then bobs around for around three days until it has lost enough weight to get airborne. :¬)

I can throw my disc golf driver(Disccraft XS, z plastic) around 400 feet. 4 months ago when I started it was about 200 feet. Disc Golf rules!

This post will probably not make the final cut of the book. Lol.

The term "Rot Gut Whiskey" came from the days before refridgeration when a medical school recieved a dead body. To store the dead body the medical school submerged the body in whiskey. When the body was used the school would sell the whiskey to the students. Just a little bit of useless trivia....

when there is a forest fired, the first trees to start growing are the lodgepole pines because their cones only open in the heat of fire

Assuming lodgepole pines grow in the area affected by fire.

Same with Ponderosa Pines (in old growth areas ONLY). Apparently, the Forest Service has figured out how to sprout saplings to be replanted in second and third growth areas.

Also, the early bird may get the worm but the early worm gets eaten, so that whole early thing is overrated:)

And the second mouse is really a life saver to the first mouse!

And when Chuck Norris goes to sleep everynight, he checks his closet for Jack Bauer. In fact, Jack Bauer and Superman once had a wrestling match. The loser had to wear his underwear on the outside of his pants.

Ok anyway, I have loads of useless facts so here's a small sample:
1.) Water towers don't actually store any water in them but are actually used to maintain water pressure in the area of the city the service by serving as the highest point and allowing water to flow "downhill".
2.) A smooth golf ball would not travel as far as a dimpled one when hit with the same amount of force.
3.) You can ride behind a bus on your bike without pedalling. (Don't try this one though)

No need to, mythbusters did it for you! The vid is somewhere on youtube :)

Something else I learned from mythbusters: Water heaters are immensely violent when they explode....like rockets, kinda.
Also, when water heaters make weird noises, it's not because they're about to explode -- it's because they have sediment built up in them...

Because the dimples on the golf ball force the air flow around them to go from laminar to turbulent and prevents what's called a seperation layer from forming early in the flow. This makes the golf ball have a smaller wake and therefore less drag. A smooth golf ball cannot go fast enough, when hit by a human with a golf club, to naturally trip from laminar to turbulent flow so the only way to do it is with the dimples. There's much more to it, but that's a start. Hope that makes sense...

Well this begs the question: Why don't airplanes have dimples?
