Here is another way also. You can also use powder coffee creamer really fine char cloth gun powder but it will explode but the board holds the ember and it's not a bad explosion also aluminum powder and I am sure there's a lot more.
Aluminum powder mixed with rust... It's called thermite!
https://rafeechemistry.weebly.com/history-and-uses.html Thermite! Was invented in 1893. In the early days it was used as a primitive form of welding… When WW2 broke out the military figured out a host of military uses for thermite.
Let’s see what other chemicals react to rust! Gun powder char cloth. Gun powder... of a mixture of sulfur, charcoal, and potassium nitrate.
Let’s see what other mixtures there are for thermite...
This is high level chemistry going back 126 years... Not a mistake... This is just an adaption of iron oxide's ability (Fe2O3 rust) to promote a highly exothermic reaction. This is chemistry, not a mistake.
Potassium nitrate a key component of gun powder. Where do you get it?
During WW2 the government confiscated all the cow manure from large dairies in the northeast. (hey grandpa! What did you do during WW2? "I hauled cow poop to west virginia.")
Why? The urine of all mammals contains high concentrations of Potassium Nitrate. The feds loaded up tons of manure and processed it for the Potassium Nitrate it contained. Where they poop, they pee!
A key ingredient in the production of Gun Powder which our military badly needed.
