George has it right. Aluminum and iron oxide react in an oxidation reduction reaction. The iron oxide reduces to iron as the aluminum oxidizes. The impact of the rusty iron ball against the striker adds enough energy to start the reaction. The reaction doesn't continue because the foil is spread out too much. There is not enough reactants in high enough concentration to keep going.
To answer this question first, what is a thermite reaction? It's a reaction that takes place when Aluminium reacts with Iron Oxide (Iron ore) to extract the Iron alone.
Equation:- Fe2O3 + Al ------> Fe + Al2O3
Note that he said "rusted" and he said that because when the Iron ball rusts, it reacts with air/air and water/water forming an oxide on its layer (Fe2O3). But still why is it exothermic? When the thermite reaction takes place, the Iron oxide loses its ions/electrons and the Aluminium gains ions/electrons. This "gaining of electrons" is called oxidation, which is exothermic.
Correct me if I'm wrong please.
well iron is just dying to accept oxygen, the rusted ball has a coating of iron oxide. oxidizing is just a super slow form of burning. when the aluminium is struck it steals the oxygen from the iron because it wants the oxygen more than the iron.. i think the resulting reactions releases light and heat and liquid or hot iron.
Aluminum acts as a fuel (reducer) iron oxide is an oxidizer. Add energy and you get a redox reaction that releases energy, aluminium oxide, and iron.

I'm surprised. Very funny and very safe experiments, thank you!
I dare write that it must take some practice to do this right, not unlike initiating a fire by rubbing pieces of wood against each other.
Love,
if im wrong reply on this
I think that the thermite isnt going straight
together, their going a liitle slanted so theyre
rubbing eachother to make friction so its can burn
the paper
Im struggling where to find two rusted ball bearings the size of apple...
I'd rather mix iron oxide and aluminum powders, then add some permanganate and glycerin.
In case anybody wants to follow this procedure, I'll instruct her/him to do this in open air, warn the neighbors, clear the area from anything flammable, and stand back. Thermite is dangerous and easily scares people who are not familiar with explosions.
Love,
Probably also start with a small amount if you've never done it before. A little goes a long way.
Wait, so thermite isn't iron, oxygen, and aluminium?
Derp Herpington Iron oxide is a compound containing iron and oxygen
Poland Ball Kind of. Thermite is roughly "Fe2O3 + 2 Al -> Al2O3 + 2 Fe + heat". Fe2O3 can be replaced with other oxides, even water. However, thermite reacts only at very high temperatures. Hence thechemistryquestion's recommendation to add an easily flammable compound to ignite it.,
Love,
Correct me if I'm wrong, but that should be due to the kinetic energy that the opposing rocks have? And all the energy being released in one small surface area... The foil acts as a conductor? Right? :D
nope, foil isn't a conductor,... the foil is needed to cause the reaction, because aluminium and iron oxyd (rust) react to iron and aluminium oxyd -> exotherm reaction -> aluminium is not a conductor in that case
but your right, you need the kinetic energy oif the smash to create the activation energy required to start thze reaktion
sorry for bad english :D
You're confusing energy with electricity
Wrong. Aluminium foil is a reducer, rust is iron oxide, an oxidizer. Combine, add heat, you get an exothermic reaction where the products are aluminium oxide, iron and heat.
Add some potassium permanganate, enlarge contact square of ingridients and it will react like hellfire. I like thermite :)
The foil acts as a conductor, causing the rust on the ball bearings to serve as an electrical charge which makes it so that when it strikes another ball bearing, the residual charge gets inflamed and causes subsequent strikes to produce sparks.
When the tap against each other while there's a sheet of paper in between, a charge is not generated, but the amount of heat it creates is enough that it momentarily burns a small hole in the paper, but not enough to set it aflame. If there was an entire book instead, the amount of explosive force produced would be equivalent to that of a small bomb. Like a pipe bomb. This is because when the balls tap against each other with the book in between, they start a small flames inside the book, but because the energy has nowhere to go, it rapidly expands as it tries to make its way out. The force generated is directly proportional to the thickness of a book. So if you used the bible, it would be enough to obliterate a bank.
Frankly, I'm quite appalled that Sick Science would teach something like this. A child could easily blow up their school with this method.
You are kidding/trolling right ?
Juraj, I'm not sure he is

I'm trying to save lives, here. Would I joke about something like that? That's why bibles are dangerous. Because they are printed in mass and usually given away freely, the paper in them is thin and serves to make it easier for the energy to disperse and implode.
All I need to know is that this can happen. I shall not bother finding out why it happens.
Isn't it because one of the ingredients for thermite is aluminum oxide ?
Aluminum just makes reactions "hotter".
what are they feeding you?
it reacts with the rust to make Al2O3 and Fe
Yay new video I love them🙌
now all you need to do is use to demolition balls with this experiment... I'd pay to see that!
This experiment should really have any 9/11 truthers tagged in it. This explains one of the main reasons that the planes were able to weaken the WTC towers enough to bring them down. The Aluminum planes slammed into the buildings at high speeds. The initial impact removed the protective covering from the iron skeleton of the towers allowing the aluminum planes to fuse with the iron creating a form of aluminum oxide aka thermite. The fire from the burning jet fuel ignited it and because it burns far hotter than the melting point of the iron used in the building structure, the exposed beams began to soften and once they failed it resulted in the pancaking of the damaged floors and the subsequent collapse. This is a great experiment
Before you display more imaginative ignorance, kindly review the summary of the final U.S. technical report on the twin towers' destruction, conveniently available on line free of charge. The public hardly needs any more fantastic technical theories related to 9/11.
Love,
Daniel Noel what part of my comment was incorrect or unreasonable? Are planes made of aluminum? YES! Was the skeleton of the towers Iron? Yes! Is aluminum oxide made when the two are combined?Yes! Was there an ignition source? Yes! Is the heat sufficient to weaken iron?Yes!
kelvin sampson Aluminium + Iron don't make Aluminium Oxide. In the right circumstances Aluminium plus rust (Iron Oxide) will give Aluminium Oxide plus Iron (the Oxygen moves from the Iron to the Aluminium) plus lots of heat. But I doubt the beams in the towers were rusty.
kelvin sampson If your comment is "correct and reasonable," then the latest U.S. technical report on the twin towers' destruction is "incorrect or unreasonable," because it does not even allude to your comment. Accordingly, your comment will have very little credibility unless and until you prove that the U.S. experts have screwed up and that you are correcting them. Your summarily stating that you are smarter than them is not convincing.
Love,
Daniel Noel Why do you guys talked about the WWC the topic in this video is what is the conclution on the expirament not solving a mistery or whatever and im not even american
Heat up the ball
foil is catalyst
To make the spark
The guy in the video is ripped!
LOL Its Look like Flint And Steel
Fe2O3+Al
Fuel!
Foil is fuel
To send an electric shock
whats the song you use in your videos?
