Introduction: How to Demonstrate Reaction Rate and Surface Area

AKA Dragons Breath -Lycopodium powder explodes into flames when it is exposed to fire in dust form. The increased surface area increases the reaction rate and you get a 6 foot long flame.

    cant you do that with flour too?

    yea you can anything dry with fine powder will ignite that includes: chocolate powder corn starch flour ...

    Try that with one of the little tanks of liquid butane you get from those lighters with the long part at the end. Open up the valve, put a flame in front of it and blow!

    I made a flamethrower using Berkin's idea and it was awesome. It produced a 5 foot flame. I also posted an instructable on it.

    I MUST LOOK!

    yep and coffe creamer too lycopodium is just way more flammable it's the stuff dr. bunhead from brainiac sprinkles around a lightbulb

    Ethylene-vinyl acetate works well for flamethrowers

    1 corn starch works best...2 man up and put it in your mouth

    Again, how is this an instructable? At the very least, show people step by step on how you put together the rig to blow the powder through the flame.
