Posted:I've been fire-twirling four about two years now, and the friend that got me into in just got a new toy- a magnesium strobe. It's a largish (about 3 inches diameter) hollow sphere or glass (crystal? something very hard and high temprature) that has a spinning wedge of metal inside.You put magnesium powdwer inside, screw it closed, then light it with a peziolectric sparker built into it. When twirled, the metal wedge spins about the inside of the sphere, creating a very cool strobe effecet. Only one is used, and you can only up in a very certain ammount of magnesium powder.

THis is half (wowcool!) and half (is this insane?!)

Posted:hey, I did that experiment too.. we did the whole burning a strip of magnesium in a crucible so we can measure the change in the mass of the residual powder...

Now what I want to know is... Did you smoke the unknown chemical?

Yeah I know.. offtopic

What exactly do I have to light on fire to get you to notice me?

Posted:An interesting concept,
however, I have been unable to find any mention of this device (or anything like it) after extensive searching of the web.
Unless I see proof of this ie. a website or at least a picture, this will be filed into the
"sounds really cool but might be made up" category.

The fact that the original poster has never replied to this thread is also disapointing, With only one post to their name their credibility is just a leeetle bit unproven.
Sorry guys, sounded good tho.

Perhaps someone wants to take a stab at making such a device........hmmmmmmmm......... I wonder.....ubbidea

Ps. I have sinusitus and a chest infection at the moment frown, hugs gratefully recieved but you might want to wear a haz-mat suit.
