Making an atomic trampoline [Nile Red]

Check out NileRed's most recent video. He made his own amorphous metal! [Final chapter]


Poster Comment:

Nile Red always striked me as a sloppy and pretentious, yet smart, spoiled rich kid. Maybe it's just a schtick. He really should have someone else cut his hair rather than his mommy.

He might be a nice guy, a Kanuk. Steve is in the UK.

This weird metal is insanely bouncy

I wonder what would happen if the ball was of the same material?

This reminds me of a funny, if not classified story...

In the late 1990s - early 2000s I worked in a secretive defense-related company in maintenance. Some of the metals I dealt with were dangerous, namely cadmium and mercury.

The cadmium was in brazing rods used to weld tempered rods (0.030-0.125, 1/32"-1/8") into into stainless steel ultrasonic drilling horns. It was a difficult task, to say the least. I built a little machine that looked like an upside-down drill press about 18 inches tall that would slowly rotate the conical horns while you applied the oxy- acetylene flame and the filler material. Problem was, the heat of the acetylene flame would anneal (make soft) the drilling rods.

IIRC, I got on my WebTV Plus dial-up internet box at home and found a low temperature eutectic (melts and flows at the same temp) filler. I think it was called Sta-Brite 8 (8% silver). It melted at a low enough temperature that you could use a propane (low temp) flame and it didn't anneal the rods. In conjunction with my machine, a trained monkey could've done the job. Boy-howdee did that make the company metallurgist mad!

His name was Charlie. He was a short, plump, bald, not very good looking, impotent 40-something man that probably still lived with his mother. "WHO THE FUCK DO YOU THINK YOU ARE CHANGING THE WAY WE DO THINGS? WHY DO YOU KNOW ABOUT EUTECTICS? WHO ARE YOU? I'LL PROVE YOU WRONG YOU, YOU, YOU, YOU PUNK! Little Charlie came up with some things to disprove me, one of them was some UV setting glue that was so dangerous that you needed to be in a space suit to deal with it. I don't know where anything went, but I suppose they went back to their bullshit ways. I was used up with the company bigwigs and the union. (IUE, International Union of Electronic, Electrical, Salaried, Machine and Furniture Workers, AFL-CIO.) I melted away, as usual. I won't tell you the local, NDAs prohibit that, but if Charlie should see this, he's still having nightmares about me LOL.

Y'all just got a section of a chapter in the book I'm not allowed to write, thanks to NDAs, and *SECRETS!* LOL.

"The Life and Times of Pacman From 1980-Present"
Chapter 1

I like hanging out with cute chicks and having sex with them.

The End.

The mercury was used in some kind of conductivity tests (I don't remember much about that, it's probably secret anyway). It came in little nasal spray-type bottles that were one pound each (16oz). All the metal used over the years is still probably on the floor and air there.

I thought you might like this, Dak, being a digit-bender, car, mech guy. My best (late) friend was a digit-bender with Raytheon in EW-1 (active electronic warfare), same as my Dad, d. 1976.

The fasteners used on the weapons (not to be confused with small arms) I worked on were cadmium coated for corrosion control, it went well with the zinc chromate.

I did some time in a sheet metal fab shop up north on IN-3 (I can't remember the name of name of the town right now, Avilla). Avilla. Welding galvanized steel is dangerous too.

My Origami skills came in handy along with my millwright experience to repair the equipment was a plus. I'm only out of a job when I want to be.

. Welding galvanized steel is dangerous too.

Over the years I've done lots of it, I know it's time to stop when it feels like I'm catching the flu. Even working outside it'll get you; the fumes roll in under the mask. Used some welding rods back in '77 that were for welding zinced items they restored the galvanizing as the bead was laid. It was on the handrail going into the basement of an old folks home in Sturgis SD
