pw pw pw posted:I looks like it would be so easy to just go flying off one of the sides of that thing and die. The only time I've been on a waterslide that steep was fully-enclosed, and even that was terrifying. I remember hearing somewhere that due to some physics trick the speed at which your travelling makes it almost impossible for you to do anything but stick to the bottom like glue. So the steeper and faster the slide the safer it is. Any math whiz out there able to confirm/deny?

Not a math/physics wizard, but it seems like if the airflow got underneath you somehow you'd flip out like an F1 car without airfoils. Presumably you stick to the water flow underneath you though and surface tension would be your friend.

Yeah, I don't expect to see his abs defined or anything, but there is clearly a bit of flab there. It's something I see in a lot of old pictures of athletes. Actually, now that I've googled it, it doesn't seem that predominant. I am crazy, please carry on.

SpazmasterX posted:Lunacy. You gotta have some sort of death wish to play with that level of electricity. Not at all! The spark from a Tesla coil doesn't really travel through you when it connects like a lightning bolt would. It just causes a tingling sensation. I have a rather diminutive one I got years ago and I still fire it up and play with it from time to time. Tesla himself gave demonstrations similar to what the guy above is doing wearing a regular suit. The jumpsuit the guy in the video is wearing is for show/crazy electric DJ equipment.  (fake edit: I know this photo is actually a double exposure.)

Speaking of Tesla Coils... Björk has harnessed this source of music for her latest album. This is what it looked like on stage during her live performances. It was one of the coolest things ever.  With each of those lightning strikes a note was produced, and she integrated it into her music. There were other instruments that symbolized air, gravity, metal, core elements, vibration, etc in her performance, it's absolutely magical. The album is Biophilia for those who are interested. Here is the song where the Tesla Coil is used to see it in live action: https://www.youtube.com/watch?v=C9Scr7wcqKk If that sparks your interest, please get the original album, the sound quality is excellent and it's a fantastic work of art. But enough spurting about my love for her :P I think she's totally badass for using the Tesla Coil for her music.

An old-fashioned spark gap Tesla Coil is a device which does NOT make most people want to get anywhere near it. The bigger ones sound like a chainsaw with a broken muffler running at full blast and in enclosed spaces will raise the ozone levels in no time. They will also emit stupid amounts of radio frequency interference. And while the secondary side (the sparks) is sort of non-lethal, the high-current, low-voltage (meaning no more than 10-15 kilovolts) primary circuit is typically uninsulated and WILL kill you quicker than most things electric. A fun fact: the Tesla Coil sparks have been used in many movies as special effect, perhaps most memorably in time travel arrival in the Terminator movies. However, the actual angry Tesla Coil sound has been heard less often, but it was used in the Raiders of the Lost Ark in the bit where the ark shoots lightning through the nazi soldiers near the end. And now for the bad-rear end part: the Nikola Tesla's idea of wireless power transmission. Many people think that this was supposed to be some sort of radio wave power transmission scheme, but that's incorrect. Tesla's idea was to build enormous Tesla Towers around the world. When operating in sync, these would move so much charge to and from the capacitive top loads that the whole Earth's ground potential would start to oscillate. After this, you would only need a correctly tuned and grounded Tesla Coil to draw power from this oscillation.  Atop his tower was perched a fifty-five ton dome of conductive metals, and beneath it stretched an iron root system that penetrated more than 300 feet into the Earth's crust. "In this system that I have invented, it is necessary for the machine to get a grip of the earth," he explained, "otherwise it cannot shake the earth. It has to have a grip… so that the whole of this globe can quiver."

Holy poo poo. I knew he was working on ways to broadcast electricity but . . . holy poo poo. Content:   Firebreathing dragon artcar. Sorry for the crappy footage. I just sort of walked up on it, so all I had was a lovely point and shoot camera. My friend is trying to get me to take a picture when it is breathing fire. He didn't realize I was getting video. quote:Teddy Lo and Ryan C. Doyle showed off their Gon KiRin (meaning light dragon) art car at New York's Robot Heart-O-Ween. The car is about 53 ft long and 23 ft tall (16 meters by 7 meters) and was originally a 1963 Dodge dump truck. Gon KiRin was outfitted with more then 2,460 ft (750 meters) of LED fixtures ad also includes a DJ booth, hydraulic neck, seating for more then 20 people and a flamethrower!

This cute little bugger right here: Was more bad-rear end than you could ever hope to be if you lived a million lifetimes. quote:Stubby served with the 102nd Infantry, 26th (Yankee) Division in the trenches in France for 18 months and participated in four offensives and 17 battles. He entered combat on February 5, 1918 at Chemin des Dames, north of Soissons, and was under constant fire, day and night for over a month. In April 1918, during a raid to take Schieprey, Stubby was wounded in the foreleg by the retreating Germans throwing hand grenades. He was sent to the rear for convalescence, and as he had done on the front was able to improve morale. When he recovered from his wounds, Stubby returned to the trenches. So, to sum up: Was all chill for an entire month's worth of constant gunfire in the trenches (my parent's dog whimpers at thunder....) Wounded by a grenade Saved lives Breathed mustard gas Warned soldiers of said gas and artillery And even captured a God-drat spy He rose to the rank of sergeant! I have friends who didn't get that far in their tours of duty. And were I in the military, I'd be drat glad to take orders from Sergeant Stubby.

I build pylons and put the wires up, we do use helicopters for live wire working but usually shut half a pylon off for small jobs. We go out on the wires like that when they're dead to add or replace spacers (the things that shop the wires touching mid-span). Enough about me though!.
