Topic: Flash Paper Idea
Message: Posted by: Russell Davidson (Mar 24, 2011 10:20AM)
Has anyone tried sticking some flash paper on a dollar coin, lighting it & then flipping it?

I was thinking it could look pretty cool if the burn time expired as it hit your hand.

But then I thought it could be rather dodgy as it will probably heat up the coin & you could burn yourself.

Comments appreciated.

Are you asking someone else to try it first??
I think it will have stopped before it reaches your hand; in fact, probably before you can flip it.
I don't think it will heat up the coin: flash paper produces very little heat. I have found it impossible to get flash paper or cotton to ignite anything else.

No, not asking for that, just wondered if someone had already tried it.

I think if you covered one side of a dollar coin it would burn long enough. I'll give it a go & see what happens.

This is very false
Flash paper creates a lot of heat! I have been seriously burned using it.
However, this depends on what "kind" of flash paper, and how much your using. I have found that black colored flash paper, burns hotter and longer than standard white.

The effect you are looking for can be accomplished by using black flash paper, because it will burn longer. Although, it (depending on how much used) burns hotter, it should heat up the coin that much(but this depends if your coin is made of a good conducting metal or not)

OK - I stand corrected. I have only used the white stuff.

No problems
I found out the hard way
Was doing a flash paper rose to real rose and did not expect it to burn differently than white colored paper. lit it up and a trip to the hospital later, I realized I had second degree burns from it.
do not use a full sheet of flash paper for that haha

Ah well that is also quite a lot of flash paper! I am much too mean to use a whole sheet.

By sticking the paper behind the coin you will retard the ignition which in your case is not good because you will not have the needed flash to cover the move.it will also leave residue on the coin.
personally I have only some non serious burns with flash paper and this happened when I tried something with glue on it.it retarded the ignition so an amount of it fell on my hand creating blisters.
the best thing to do in my opinion is the classic production of a coin with fire.you will not need set up,it will work easier and you will have best results.

Love berger's torn and restored cig paper with a prediction on it. I always right applause please which is what they are usually doing anyway.

This is a very good point worth repeating!! Black flash paper burns slower and hotter! I have burnt myself and I accidentally caused a second degree burn to one of my assistants when using black flash paper. One of my dealers, spookclub.com, actually stopped carrying it due to hazard concerns and I have stopped using it all together because of my experiences.

I totally disagree with that statement. Flash paper produces a LOT of heat. I should know because I'm the company director of http://www.flashmagic.co.uk. We deal with LOTS of flash products and to say that flash paper produces "very little heat" is just nonesense! Have you tried holding flash paper when it's igniting?

Any additive to plain white paper will retard the burn time including colored flash paper and white paper that burns different colors. It seems the real problem with heat is in the concentration of the flash paper. If you wad a sheet up into a small ball it will burn fast and produce a heat that is concentrated in a very small area. If you take that same sheet of flash paper and lay it on a glass surface it will burn a lot slower and leave less heat in any specific area due to it being spread out. The retardation of burn time in this case is due to less oxygen being able to get to the back side of the paper.

If it is "stuck" to a coin the burn time will be retarded by only one side being exposed and the material securing it to the coin. Will that small a piece produce enough heat to be burned? If you left it on your hand with the flash paper burning against your skin, of course. Will it heat the coin enough while in the air to not be able to handle it? Probably not. Experiment safely, use a pyrometer to check the coins temperature when it hits the table and go from there.
