I store all my flash supplies (paper, string, cotton) in the plastic case that cd spindles come with. No top, but I think its better to let it breathe.

It's sure convenient, in my case anyhow.

A quick story about storing flash paper...

Blackpool... Friday night. It is the opening dealers show for the 2006 convention. As you walk through the Horseshoe Hall doors there are dealers to the left and right. I was seven booths in on the left.

I was demonsrating my Hot Leads wallet and my Alien Spinning thing and generating quite a crowd around my booth.

Now, crowds often move from booth to booth but none so fast as the one this night. To my right I saw a huge flame. I heard some screams and my crowd left like somebody yelled "free money".

I figured someone was demonstrating bigger fire than I and what ever it was was going to sell big. When I say bigger fire I mean a 12 foot flame shooting up and above the crowd's heads. Then the flame turned to a steady 4 foot flame and people started stomping ther feet around the booth and others moved away.

You get the idea... someone had left a box of flash paper uncovered at their booth and a spark from another fire gimmick set the box on fire. It burned a 2 foot hole into the carpet and it smelled awful.

Storing flash paper in a safe place is a must when you do not need it. Especially when there is a box that is full of it...

Sunday... a man who looked like he had a nice sun tan on the side of his face and arm came to my booth and purchased my Igniter gimmick. It was him.

Wisdom comes from experience. This man will never store flash paper the same way again.

I didn't see it happen on the Friday night, but I saw what was left of the carpet and walls. Not good. I doubt it will be allowed there next year. They banned the demonstration of fire at the rest of the convention. It was a freak accident that could have been easily avoided.

Jim, I didn't know you had the Ignitor up in Blackpool?

Jim,

that's a great story and made me run to cover my small box of paper/cotton. Actually I should know better...

Once I had cookie tin with the cover off filled with flash paper/cotton.
It was on my desk next to my computer in my practice room. I happened to forget it was there and I was smoking (DUH). The cover was off and I didn't even realize what I was doing but ashed in the tin.

One can imagine the eruption that caused. Though I was not hurt, it scared the bejezus out of me so much so that I stayed away from flashpaper for a few weeks.

Jim's right, make sure the stuff stays in a safe container, and covered, and for God's sake, if you have to smoke, don't do it near your box of flash material.

Pyro can self-ignite if old. Ask the former president of the Magische Zirkel Germany, who had to make this experiment in the 80s and burned down his house!

First, I have my pyros wet and deepfrozen, take out the quantity that I need, dry it in my shower (if it should ignite, it can't burn anything around) or at least, lying on a plate in the middle of the room. The dry stuff I put into a PLASTIC airtight container (like for fitness supplements). If you have a metal one and for whatever reason it ignites, you have a BOMB.

The petrol for the torches and the pyros are, of course, separate! I never leave the petrol (in the special security bottles) nor the pyros overnight in the theatre, but have them in my apartement/hotel room. In case there is a fire in the theatre, they'll first ask you...

BE EXTREMELY CAREFUL! ALWAYS! And you should have an insurance that covers accidents with your fire act or props, too!

But even if they are stored in a plastic container, it will still cause a huge explosion, it doesn't matter what material it is in really, only how airtight and how strong it is. It also depends on the shape of the container. You should store it in a container that is not airtight, that's what I think, not sure though. I just dry out my cotton on a window sill (we have REALLY thick walls) and then carry it in a ziplock bag.

"Pyro can self-ignite if old."- Wolf Fisher

Hi... I have never heard of this before. Can you elaborate?
I had worked behind the counter at a magic store for 20 years and never knew anyone that this has happened to, or why it happened. I had heard that it can but it always seemed like an urban legend. I even had a very old magi come into the store and ask for some new flash paper as the stuff he had was over 30 years old and getting ugly.
Truly there must be some kind of ignition to have flash paper just go up?

Kind Regards,
Jim

Actually a friend of mine used to store his premeasured flash powder for his flashpots in 35mm containers. One day while uncapping one there was a static spark inside the container and, well, it was not a pleasant experience.

No fatalites, but no eyebrows for awhile either...

Sounds like someone wasn't properly grounded Smile

I guess proper de-static techniques (like the grounded wrist bands used in computer assembly) should be used in all technical work- including pyrotechnic setup. Thanks for the warning!

Exploding tins!

there is a finite amount of energy in your flash paper, and a minimum energy required to fragment your tin. if there isn't enough flash in the tin, it won't turn into a bomb

The most likely outcome from an accidental ignition in a closed tin is not so dramatic (how much do you keep in one tin anyway?). An open tin will allow the paper to burn and you'll get a proportional flame

Oh, did you guys ever have fireworks when you were kids? Just use some common sense.

Anyone know what the flash point of flash paper is?

I know what the flash point of paper is and it's much lower than one would expect. This business about storing it in "tins" should be quashed now. It is unsafe and utterly unreliable to store flash paper in ANY type of cookie tin, or light weight metal box. I say this because there is aluminum present in these as well as other metals that cause oxidation. Basically, your paper starts to turn a funky color of yellow and then break down much faster when stored in a metal conatiner with no ventilation. Guess what the bi-product/residual stuff is in the tin. None other than Nitrocelluose! This is what gives flash paper it's Flash! This stuff is actually more unstable than Nitro Glycerine and can ignite from being stored in a vacuum enviroment and then suddenly exposed to air. I know this because I've seen it happen on a large scale. No spark, no Static. Nothing. Just air.

This is [robably what happened to your friend with the photographers film canisters.

Bottom line is be careful and always respect this stuff!

For the record I keep mine in plastic 'business card' boxes, not air tight or metal, just convenient.

So what is the flash point? 150 dec C?
