1925 book

Post by Mark » Thu Feb 17, 2005 2:11 pm

Just a very old book that was donated to the library, we will either sell it in the book store or trash it, it's so old. But I saw this simple demonstration, and although it is not earthshaking, it does present a different perspective of the "oxidizer" and the "fuel."
I'm always looking through donated physics books or anything scientific in case there is something or some idea that would be of interest.
In this particular series of books that were donated, I kept hoping to find some stuff on pulsating combustion. But since it was printed in 1925, ...

Here's another perspective, a little more obscure but the same idea.

that flame walking from fuel to oxidiser is interesting.
the second experiment, to have the flame in the fuel, may proof the same but sure looks more dramatic

I really like the first experiment, certainly made me think about it. I have a feeling it would destroy the minds of some of the lower ability science groups at my school, that is of course, after they learnt the difference between fuel and oxidizer. Thanks Mark, interesting post.

Experience speaks more then hypothesizing ever can. More-so in chemistry.

To me, it reminds me of bananas, that is, if bananas were as rare as caviar, everyone would be eager to eat bananas. That's the way of the world, supply and demand. And so it is with fuel and air, it's just a matter of balance, who is to say which is fuel and which is oxidizer. I love things that bend the mind.
At first I agreed with Ben and the first model, but then the second demonstration, if you spend some time and think about it, becomes more telling, more obvious, for how many have thought about a stream of air burning, as if it were a Bunsen burner running on gas.
