How to Demonstrate Reaction Rate and Surface Area

video How to Demonstrate Reaction Rate and Surface Area

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.

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.

Bitty, videos and slideshows are not meant to be Instructables. Rather they are meant to be a place where you can document a build/something you did without full explanations and details. Don't believe me? check out [http://www.instructables.com/id/The-InstructableSlideshowVideo-Tabs..../ this instructable]. The rig is very simple, a tube with some lycopodium powder in it aimed at a flame.

If you have allergies this stuff can put you down. Used this in a chem lab and within two hours was drooling out every facial orifice except my ears. I like your other demos. Will be using a few in class

That was insane! Awesome job. Can you show how to do it, I would want to try.
